- Source: N-acetylneuraminate 7-O(or 9-O)-acetyltransferase
In enzymology, a N-acetylneuraminate 7-O(or 9-O)-acetyltransferase (EC 2.3.1.45) is an enzyme that catalyzes the chemical reaction
acetyl-CoA + N-acetylneuraminate
⇌
{\displaystyle \rightleftharpoons }
CoA + N-acetyl-7-O(or 9-O)-acetylneuraminate
Thus, the two substrates of this enzyme are acetyl-CoA and N-acetylneuraminate, whereas its 3 products are CoA, N-acetyl-7-O-acetylneuraminate, and N-acetyl-9-O-acetylneuraminate.
Nomenclature
This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:N-acetylneuraminate 7-O(or 9-O)-acetyltransferase. Other names in common use include N-acetylneuraminate 7(8)-O-acetyltransferase, sialate O-acetyltransferase, N-acetylneuraminate 7,8-O-acetyltransferase, acetyl-CoA:N-acetylneuraminate-7- or 8-O-acetyltransferase, acetyl-CoA:N-acetylneuraminate-7- and/or 8-O-acetyltransferase, glycoprotein 7(9)-O-acetyltransferase, acetyl-CoA:N-acetylneuraminate-9(7)-O-acetyltransferase, N-acetylneuraminate O7-(or O9-)acetyltransferase, and acetyl-CoA:N-acetylneuraminate-9(or 7)-O-acetyltransferase.
