UDP-N-acetilglukozamin kinaza (EC 2.7.1.176, UNAG kinaza, zeta toksin, toksin PezT, ATP:UDP-N-acetil-D-glukozaminska 3'-fosfotransferaza) je enzim sa sistematskim imenom ATP:UDP-N-acetil-alfa-D-glukozamin 3'-fosfotransferaza.^[1]^[2] Ovaj enzim katalizuje sledeću hemijsku reakciju

ATP + UDP-N-acetil-alfa-D-glukozamin

\rightleftharpoons

ADP + UDP-N-acetil-alfa-D-glukozamin 3'-fosfat

Ovaj protein je toksična komponenta toksin-antitoksin (TA) modula. Fosforilacija UDP-N-acetil-D-glukozamina dovodi do inhibicije EC 2.5.1.7, UDP-N-acetilglukozamin 1-karboksiviniltransferaze.
