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 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.

<span class="mw-page-title-main">Zeta toxin protein domain</span>

In molecular biology, the protein domain Zeta (ζ) toxin refers to a protein domain found in prokaryotes, which acts as a UDP-N-acetylglucosamine kinase. Its function is to inhibit cell wall biosynthesis and it may act as a bactericide in nature. It is also thought that Zeta toxin induces reversible protective dormancy and permeation to propidium iodide (PI).
