ENZYME entry: EC 2.4.99.4
| Accepted Name |
|---|
| Beta-galactoside alpha-2,3-sialyltransferase.
|
| Alternative Name(s) |
|---|
| CMP-N-acetylneuraminate-beta-galactosamide-alpha-2,3-sialyltransferase. |
| Reaction catalysed |
|---|
| CMP-N-acetylneuraminate + beta-D-galactosyl-1,3-N-acetyl-alpha-D-galactosaminyl-R <=> CMP + alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,3-N-acetyl-alpha-D-galactosaminyl-R |
| Comment(s) |
|---|
- The acceptor is Gal-beta-1,3-GalNAc-R, where R is H, a threonine or
serine residue in a glycoprotein, or a glycolipid.
- Lactose can also act as acceptor.
- May be identical with EC 2.4.99.2.
