WebDec 11, 2024 · We used the Collagen Toolkits, libraries of triple-helical peptides that embrace the entire helical domains of collagens II and III, to map MMP-3 interaction sites. Webticellular organisms. Collagen is constituted by three polypeptide chains (a-chains) that form a triple-helix structure. More than 27 forms of collagen are present in animal tissues. Some of them (types I, II, III, V, and XI) are arranged in fibrils and are found in tissues that must be able to resist tensile, shear, or compression forces,
WebTriple-helical conformation has been proposed to be important for cellular activities, such as adhesion and activation, extracellular matrix assembly, and enzyme function, such as hydroxylation of collagen Lys and Pro residues and matrix metalloproteinase (MMP) catabolism of native collagens. WebHelices can be either right-handed or left-handed. With the line of sight along the helix's axis, if a clockwise screwing motion moves the helix away from the observer, then it is called a right-handed helix; if towards the observer, then it is a left-handed helix.

In molecular biology, the collagen triple helix or type-2 helix is the main secondary structure of various types of fibrous collagen, including type I collagen. In 1954, Ramachandran & Kartha (13, 14) advanced a structure for the collagen triple helix on the basis of fiber diffraction data.
