| Cat# | DIA-862 |
| Descriptions | ST3 Beta-Gal Alpha-2, 3-Sialyltransferase 3 (ST3GAL3) preferentially sialylates type 2 N-acetyllactosamine chains on glycoproteins, mediates α-2,3 linked sialic acid addition, and plays important roles in immune cell trafficking and nervous system development. |
| Applications | ST3 Beta-Gal Alpha-2, 3-Sialyltransferase 3 (ST3GAL3) serves as a raw material for immune cell glycosylation detection kits and nervous system glycan assay reagent development. |
| CAS No. | 24-3-61303 |
| Enzyme Commission Number | EC 2.4.3.6 |
| Enzyme Source | Trichoplusia ni, High Five (baculovirus)-derived human ST3GAL3 protein. |
| Reaction | a beta-D-galactosyl- (1->4)-N-acetyl-beta-D-glucosaminyl derivative + CMP-N-acetyl-beta-neuraminate = an N-acetyl-alpha-neuraminyl- (2->3)-beta-D-galactosyl- (1->4)-N-acetyl-beta-D-glucosaminyl derivative + CMP + H+ |
| Activity Definition | Measured by its ability to transfer Neu5Ac from CMP-Neu5Ac to N-Acetyllactosamine. |
