Biosynthesis of Chondroitin Sulfate
A microsomal preparation from chick embryo cartilage has been shown to catalyze the incorporation of sulfate-36S from 3’-phosphoadenosine 5’-phosphosulfate-3% into microsomal glycosaminoglycan. This enzyme preparation is the same preparation that previously has been shown to catalyze the formation of chondroitin (nonsulfated) from sugar nucleotide precursors. The microsomal sulfate acceptor app...
متن کاملBiosynthesis of Chondroitin Sulfate
The role of phospholipids in the activity of UDP-D-galactose:D-xylose galactosyltransferase (galactosyltransferase I) from embryonic chick cartilage was investigated. Phospholipase C treatment of particulate galactosyltransferase I caused inactivation of this enzyme to the extent of 60 to 70% as well as hydrolysis of 75 to 80% of the membrane phospholipids. Addition of phospholipid restored act...
متن کاملBiosynthesis of chondroitin sulfate. Organization of sulfation.
The potential relationship of an intact membrane organization for the synthesis of chondroitin and chondroitin 4-sulfate was examined after modification of a mouse mast cell microsomal system with the nonionic detergent, Triton X-100. The results indicated that Triton X-100 had no effect on the rate of polymerization but had a slight effect on the size of glycosaminoglycan chains. An "all or no...
متن کاملThe Biosynthesis of Chondroitin Sulfate by a Cell-free Preparation.
The biosynthesis of the acid mucopolysaccharide, hyaluronic acid, has been demonstrated in cell-free preparations derived from Group A streptococci (1, 2) and embryonic rat skin (3). In keeping with their function as glycosyl donors in many systems, the uridine nucleotides, uridine 5’-diphosphate-N-acetyln-glucosamine and UDP-n-glucuronic acid, have been shown to be the requisite intermediates ...
متن کاملChondroitin sulfate
While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a n...
