| Accepted name: |
polysialic-acid O-acetyltransferase |
| Reaction: |
acetyl-CoA + an α-2,8-linked polymer of sialic acid = CoA + polysialic acid acetylated at O-7 or O-9 |
| Systematic name: |
acetyl-CoA:polysialic-acid O-acetyltransferase |
| Comments: |
Acts only on substrates containing more than 14 sialosyl residues. Catalyses the modification of capsular polysaccharides in some strains of Escherichia coli. |
