In enzymology, a N-acylmannosamine kinase (EC 2.7.1.60) is an enzyme that catalyzes the chemical reaction
- ATP + N-acyl-D-mannosamine ADP + N-acyl-D-mannosamine 6-phosphate
Thus, the two substrates of this enzyme are ATP and N-acyl-D-mannosamine, whereas its two products are ADP and N-acyl-D-mannosamine 6-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-acyl-D-mannosamine 6-phosphotransferase. Other names in common use include acylmannosamine kinase (phosphorylating), acetylamidodeoxymannokinase, acetylmannosamine kinase, acylaminodeoxymannokinase, acylmannosamine kinase, N-acyl-D-mannosamine kinase, N-acetylmannosamine kinase, and ATP:N-acetylmannosamine 6-phosphotransferase. This enzyme participates in aminosugars metabolism.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2AA4.
