7655169-10	1995	The catalytic domain of the cloned sequence was expressed in transfected cells and was shown to be competent in mediating the specific synthesis of sialic acid alpha 2,3 to Gal(beta 1,3)GalNAc-R. Genomic sequences for SiaT-4a were also isolated and examined.	N-acetylgalactosaminuronic acid	186-192	ST3 beta-galactoside alpha-2,3-sialyltransferase 1	Homo sapiens	218-225
