Available in PDF, EPUB and Kindle. Book excerpt: The solution-phase association of biological molecules to form aggregates has been studied from a variety of perspectives, such as the flocculation of polymers, association of colloids and the aggregation of proteins. The latter subject has been the target of particular attention, mainly because of its importance in biomedical applications as well as its implication in diseases such as spongiform encephalopathies and Alzheimer's disease. Investigating protein aggregation at a fundamental level, however, is often complicated by the poorly defined structures of the aggregation products formed, as well as by the difficulty in working with biological systems. In this thesis, studies of Type-I collagen, a rod-like protein which can undergo 'in vitro' aggregation into highly-ordered protein structures, have been carried out with a view towards determining the mechanisms by which protein aggregates form. Two particular aggregate structures have been investigated. The first, a block-like aggregate called segmental long spacing collagen, was formed by the addition of nucleotide triphosphates to collagen monomers. By analyzing aggregate structures, formation kinetics and growth thermodynamics, it was concluded that these aggregates form via a hierarchical growth mechanism involving the formation of a stable intermediate and subsequent fusion of these intermediates. The second form of aggregate investigated was a fibril referred to as fibrous long spacing collagen. In this case, particular insight was made into elucidating the structure of these fibrils using the atomic force microscope. Results obtained again suggest that this aggregate forms via a hierarchical mechanism, first forming stable 'protofibrils', which then merge in a complex manner to produce the final structure. In the final Part of this thesis, the capabilities of the atomic force microscope in performing imaging of dynamic, biological processes in real time was examined, and was used to image the enzymatic digestion of collagen fibrils by the protein collagenase. The utility of the atomic force microscopy for 'in situ' investigation of complex processes such as collagen formation is discussed with a view towards applying this technique to future work.

Book excerpt: Collagen is the major structural protein in mammals, and forms the basis of a variety of tissues essential for animal life, including bone, skin, teeth, cornea, tendon, and others. It self-assembles---both in vivo and in vitro---into a variety of biologically important structures, and this self-assembly process is highly dependent on solution pH, ionic strength, and the concentration of the collagen monomer. Kinetic studies demonstrating these dependencies are presented for the formation of the most important aggregate, native type collagen. The cold dissociation of collagen that does not contain complete non-helical telopeptide regions is also demonstrated. Based on these studies, five different types of collagen intermediates are identified and a partially hierarchical fibrillogenesis mechanism is proposed, along with a detailed kinetic model. In order to further understand collagen fibrillogenesis at a molecular level, a previously predicted structure of the collagen monomer is completely relaxed using condensed phase molecular dynamics simulations. For validation purposes, several experimentally solved model collagen structures are simulated in the same way, and the simulation results agree with the crystal structures to within the experimental error. Therefore, a structure of the collagen monomer is proposed that comprises the most complete model currently developed. This model forms the basis for two sets of simulations aimed at explaining the formation of several of the polymorphisms of collagen. First, a three-dimensional analysis of the interactions between collagen monomers in fibrillar aggregates is presented, including hydrophobic-hydrophobic and electrostatic interactions. An examination of these interactions as a function of overlap between monomers demonstrates the origin of the topological regularity in native type collagen. Second, a detailed molecular model for formation of segmental long spacing crystallites of collagen is presented, involving bridging of in-register collagen monomers by nucleotide triphosphate moieties at colocalized acidic and basic residues. The proposed model is confirmed using molecular mechanics and dynamics simulations.

Book excerpt: Being the most abundant protein in the body, by mass, type I collagen provides the building blocks for tissues such as bone, extra-cellular matrix, tendons, cornea, etc[1-3]. The ability of a single protein to create structures with such various mechanical properties is not fully understood. Before one can engineer and assemble a complex tissue, such as cornea, the mechanisms underlying the formation and assembly, mechanical properties, and structure must be investigated and quantified. The work presented herein contains an extensive study of Type I collagen from the molecular to the tissue level. The engineering of collagenous tissues that mimic the mechanical and optical properties of native human cornea have been performed by a number of groups[4-7]. In all of these studies, the corneal-mimicking tissues have been created using a number of methods including repeated flow casting. To date, the ability to create self-assembled corneal tissue has not been achieved. Understanding the mechanisms of formation of native cornea will not only bring us closer to achieving self-assembled transplantable corneal tissue but will also aid in the engineering of all collagenous tissues and other structures comprised of filamentous units. Recently, the study of type I collagen has primarily focused on the tissue, fiber, and fibril scale[2, 8-21]. Grant, et al.[20] measured the elastic modulus of collagen fibrils in various solutions and found that by increasing ion concentration, in the solution around the fibril, the elastic modulus increased. The solution dependent behavior of the elastic modulus of collagen fibrils was measured but the cause of the dependence was unknown. Grant et al. state that due to the complex nature of the interactions between collagen fibrils and aqueous solutions, the exact cause of this effect is difficult to determine.

This book was released on 2013-06-29 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collagen is a fascinating protein not only because of its ubiquitous occurrence in multicellular animals, but also because of its unique chemi cal structure. As the predominant constituent in bone, cartilage, skin, tendon, and tooth, it is not surprising that collagen is of interest to anatomists, biochemists, biomedical engineers, cell biologists, dermatolo gists, dental surgeons, leather chemists, orthopedic surgeons, physiologists, physicians, zoologists, and a host of others. This book was planned to provide an up-to-date comprehensive survey of all aspects of biochemistry of collagen. The recent discovery of genetically distinct collagens with tissue specificity has opened a new era in collagen biochemistry, and Karl Piez discusses this in the opening chapter on primary structure. In the next chapter, Ramachandran and Rama krishnan deal with the molecular structure of collagen, placing special emphasis on the conformational aspects of its polypeptide chains. Follow ing the consideration of primary and secondary structure of collagen, the three-dimensional arrangement of collagen molecules in the fibrils is covered by Miller in Chapter 3. Collagen is generally in the insoluble state in the living organism due to the cross-linking of individual molecules, and Tanzer describes the various aspects of this cross-linkage in Chapter 4. The biosynthesis of collagen is discussed in depth by Prockop and his colleagues.

This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the techniques of electron microscopy have developed so widely and rapidly that they now cover the fields of research once the unique ll:panage of sister research techniques such as biochemistry, physiology, immunology, X-ray diffraction, etc. It is now possible to reach molecular and submolecular levels, making this technique indispensable in every type of research. Electron microscopy alone often provides enough information to solve given problems. In the field of the connective tissue matrix, knowledge of the molecular structure of collagen, pro teoglycans and elastin and their interaction has been to a large extent elucidated by electron microscopy. The field over which electron microscopy ranges in the investigation of the connective tissue matrix is so wide that the aim of this volume is to collect the main ultrastructural acquisitions disseminated in various journals and monographs in one book. The intent ofthis volume is to: (a) integrate different and new microscopic methods and review the results of such an integrative approach; (b) present a comprehensive ultrastructural account of selected aspects of the field; (c) point out gaps or controversial topics in our knowledge; (d) outline pertinent future research and expansion of the subject.

Available in PDF, EPUB and Kindle. Book excerpt: Biochemistry of Collagens, Laminins, and Elastin: Structure, Function, and Biomarkers provides a comprehensive introduction to collagen and structural proteins. Type I collagen is one of the most abundant molecules in the body, playing essential roles in different tissues, particularly bone and skin. A key aspect of type I collagen is its post-translational modifications which are essential for correct synthesis and structural integrity of collagens, for tissue-specific functionality, as well as for application as biomarkers of different pathologies. This volume summarizes current data on key structural proteins (collagens, laminins and elastin), reviews how these molecules affect pathologies, and describes selected modifications of proteins that result in altered signaling properties of the original extracellular matrix component. Further, it discusses the novel concept that an increasing number of components of the ECM harbor cryptic signaling functions that may be viewed as endocrine functions. Additionally, it highlights how this knowledge can be exploited to modulate fibrotic disease. - Provides a comprehensive introduction to collagen and structural proteins - Provides insight into emerging analytical technologies that can detect biomarkers of extracellular matrix degradation - Includes a chapter dedicated to the biomarkers of structural proteins - Contains insights into the biochemical interactions and changes to structural composition of proteins in disease states

Available in PDF, EPUB and Kindle. Book excerpt: In the ten-year interval since the first edition of this volume went to press, our knowledge of extracellular matrix (ECM) function and structure has enor mously increased. Extracellular matrix and cell-matrix interaction are now routine topics in the meetings and annual reviews sponsored by cell biology societies. Research in molecular biology has so advanced the number of known matrix molecules and the topic of gene structure and regulation that we won dered how best to incorporate the new material. For example, we deliberated over the inclusion of chapters on molecular genetics. We decided that with judicious editing we could present the recent findings in molecular biology within the same cell biology framework that was used for the first edition, using three broad headings: what is extracellular matrix, how is it made, and what does it do for cells? Maintaining control over the review of literature on the subject of ECM was not always an easy task, but we felt it was essential to production of a highly readable volume, one compact enough to serve the the student as an introduction and the investigator as a quick update on graduate the important recent discoveries.

Available in PDF, EPUB and Kindle. Book excerpt: The complex and critical process of extracellular matrix (ECM) assembly is described in this book. Assembly may involve molecules interacting with molecules of the same matrix class, such as in collagen, or interactions between different ECM molecules, such as in basement membranes. The text shows how this is driven by structural information within the matrix monomer. This information will be of interest to cell, developmental, and molecular biologists, biochemists, biophysicists, and biomedical researchers involved in macromolecular assembly, biological macromolecules, and extracellular matrix. Addresses assembly of most of the known classes of extracellular matrix macromolecules Discusses higher order structures produced by ECM Gives important concepts in ECM and cell-matrix interactions, Protein structure and protein-protein interactions, Development and tissue remodeling
