4-O-Sulfation of GalNAc is a high frequency modification of chondroitin sulfate and dermatan sulfate (DS), and three major GalNAc 4-O-sulfotransferases including dermatan 4-O-sulfotransferase-1 (D4ST-1) and chondroitin 4-O-sulfotransferases-1 and -2 (C4ST-1 and -2) have been identified. 4-O-Sulfation of GalNAc during DS biosynthesis had long been postulated to be a prerequisite for iduronic acid (IdoUA) formation by C5-epimerization of GlcUA. This hypothesis has recently been argued based on… CONTINUE READING
