Collagen hydroxylase
WebMar 1, 2003 · The collagen prolyl 4-hydroxylases (P4Hs), enzymes residing within the endoplasmic reticulum, have a central role in the biosynthesis of collagens. In addition, cytoplasmic P4Hs play a critical role in the regulation of the hypoxia-inducible transcription factor HIF α. Collagen and HIF P4Hs constitute enzyme families as several isoenzymes … WebThe extent of Lys hydroxylation of collagen is much more variable than that of Pro. It varies from one genetic type to another ( 5) and, even within the same genetic type I collagen, it significantly varies depending on the tissue and the tissue’s physiological conditions.
