15274643-1	2004	A large family of uridine 5"-diphosphate (UDP)-alpha-N-acetylgalactosamine (GalNAc):polypeptide N-acetylgalactosaminyl transferases (ppGalNAc Ts) initiates mucin-type O-glycan biosynthesis at serine and threonine.	N-acetylgalactosaminuronic acid	76-82	mucin	Canis lupus familiaris	156-161	
6449507-3	1980	Canine submaxillary gland microsomes have been shown to catalyze the following reaction: UDP-GlcNAc + Gal beta 1-3GalNAc-X leads to Gal beta 1-3(GlcNAc)GalNAc-X + UDP where X is porcine or ovine submaxillary mucin polypeptide or a low molecular weight substituent.	N-acetylgalactosaminuronic acid	114-120	mucin	Canis lupus familiaris	208-213	
6449508-9	1980	Preliminary evidence has been obtained indicating that sialic acid linked alpha 2-6 to GalNAc or L-fucose linked alpha 1-2 to Gal inhibit the action of the beta 6-N-acetylglucosaminyltransferase on Gal beta 1-3GalNAc-porcine submaxillary mucin polypeptide.	N-acetylgalactosaminuronic acid	87-93	mucin	Canis lupus familiaris	238-243
