摘要: N-Acetylglucosaminyltransferase III, IV and V activities were assayed in various rat tissues hepatomas using the same fluorescence-labeled sugar chain, GlcNAc beta 1-2Man alpha 1-3-(GlcNAc 1-6)Man 1-4GlcNAc 1-4GlcNAc-2-aminopyridine as a substrate. The N-acetylglucosaminyltransferase III activity toward substrate is highest most including primary hepatoma. A relatively higher for GnT-V found small intestine, serum hepatoma compared to that of GnT-IV. Some kinetic properties these enzymes crude extracts also determined.
