N-acetylgalactosamine kinase
In enzymology, a N-acetylgalactosamine kinase (EC 2.7.1.157) is an enzyme that catalyzes the chemical reaction
- ATP + N-acetyl-D-galactosamine ADP + N-acetyl-alpha-D-galactosamine 1-phosphate

Thus, 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. The systematic name of this enzyme class is ATP:N-acetyl-D-galactosamine 1-phosphotransferase. Other names in common use include GALK2, GK2, GalNAc kinase, and N-acetylgalactosamine (GalNAc)-1-phosphate kinase.
