Gly-x-y repeats

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. It consists of a triple helix made of the repetitious amino acid sequence glycine-X-Y, where X and Y are frequently WebCOL4A1 (collagen type IV α 1 chain) belongs to the collagen family. It has an N-terminal 7S domain, a C-terminal globular domain (NC1), and the central triple helical part with short interruptions of the Gly-X-Y repeats [ 1]. It is an important constituent of type IV collagen in the basement membrane [ 2].
