UDP-N-acetylglucosamine kinase (EC 2.7.1.176, UNAG kinase, zeta toxin, toxin PezT, ATP:UDP-N-acetyl-D-glucosamine 3'-phosphotransferase) is an enzyme with systematic name ATP:UDP-N-acetyl-alpha-D-glucosamine 3'-phosphotransferase.[1][2] This enzyme catalyses the following chemical reaction
- ATP + UDP-N-acetyl-alpha-D-glucosamine [math]\displaystyle{ \rightleftharpoons }[/math] ADP + UDP-N-acetyl-alpha-D-glucosamine 3'-phosphate
The phosphorylation of UDP-N-acetyl-D-glucosamine causes the inhibition of enzyme EC 2.5.1.7, UDP-N-acetylglucosamine 1-carboxyvinyltransferase.
These enzymes are found as part of plasmid-encoded[3] and chromosomal[4] bacterial toxin-antitoxin systems.
