| othername | CMP-N-acetylneuraminate-beta-galactosamide-alpha-2,3-sialyltransferase 4, Alpha 2,3-ST 4, Beta-galactoside alpha-2,3-sialyltransferase 4, 2.4.99.-, Alpha 2,3-sialyltransferase IV, Gal-NAc6S, Gal-beta-1,4-GalNAc-alpha-2,3-sialyltransferase, SAT-3, ST-4, ST3Gal IV, ST3GalIV, ST3GalA.2, STZ, Sialyltransferase 4C, SIAT4-C, ST3GAL4, CGS23, NANTA3, SIAT4C, STZ |
| Background | It may catalyze the formation of the NeuAc-alpha-2,3- Gal-beta-1,3-GalNAc- or NeuAc-alpha-2,3-Gal-beta-1,3-GlcNAc- sequences found in terminal carbohydrate groups of glycoproteins and glycolipids. It may be involved in the biosynthesis of the sialyl Lewis X determinant. Also acts on the corresponding 1,3- galactosyl derivative. |
