ID   2.1.1.402
DE   sialate 8-O-methyltransferase.
AN   N-acetylneuraminate 8-O-methyltransferase.
CA   N-acetylneuraminate + S-adenosyl-L-methionine = N-acetyl-8-
CA   O-methylneuraminate + S-adenosyl-L-homocysteine + H(+).
CC   -!- The enzyme has been isolated from gonads of the starfish Asterias
CC       rubens.
CC   -!- It methylates N-glycolylneuraminate with equal specificity.
CC   -!- Oligosaccharides containing N-acetyl-alpha-neuraminyl-(2->3)-beta-D-
CC       galactosyl-(1->3)-N-acetyl-D-galactosyl structures are also
CC       methylated.
