Monosialoganglioside sialyltransferase
Template:Short description Template:Infobox enzyme In enzymology, a monosialoganglioside sialyltransferase (Template:EC number) is an enzyme that catalyzes the chemical reaction
- CMP-N-acetylneuraminate + D-galactosyl-N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-D-glucosylceramide CMP + N-acetylneuraminyl-D-galactosyl-N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-D-glucosylceramide
The 2 substrates of this enzyme are CMP-N-acetylneuraminate and D-galactosyl-N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-D-glucosylceramide, whereas its 2 products are CMP and N-acetylneuraminyl-D-galactosyl-N-acetyl-D-galactosaminyl-(N-acetylneuraminyl)-D-galactosyl-D-glucosylceramide.
This enzyme belongs to the family of transferases, specifically those glycosyltransferases that do not transfer hexosyl or pentosyl groups. The systematic name of this enzyme class is CMP-N-acetylneuraminate:D-galactosyl-N-acetyl-D-galactosaminyl-(N-ac etylneuraminyl)-D-galactosyl-D-glucosylceramide N-acetylneuraminyltransferase.
