Biosynthesis of collagen
WebJan 1, 2005 · Collagen is synthesized in the endoplasmic reticulum (ER) as procollagen, which is the precursor protein that bears propeptide domains at either end of the triple helical domain. The processes by which procollagen is synthesized in the lumen of the ER include unique steps that are not found in the biosynthesis of globular proteins. WebBiosynthesis of collagen is a very complex process consisting in both stages of albumen synthesis and unique processes that take place only during biosynthesis of collagen. This process takes place in fibroblasts …
