In enzymology a N-acetylgalactosamine kinase (EC 2.7.1.157) is an enzyme that catalyzes the chemical reactionATP + N-acetyl-D-galactosamine ADP + N-acetyl-alpha-D-galactosamine 1-phosphateThus the two substrates of this enzyme are ATP and N-acetyl-D-galactosamine whereas its two products are ADP and N-acetyl-alpha-D-galactosamine 1-phosphate.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor.
