Phosphinothricin acetyltransferase

Phosphinothricin acetyltransferase (EC 2.3.1.183, PAT, PPT acetyltransferase, Pt-N-acetyltransferase, ac-Pt) is an enzyme with systematic name acetyl-CoA:phosphinothricin N-acetyltransferase.^[1][2] This enzyme catalyses the following chemical reaction

acetyl-CoA + phosphinothricin ${\displaystyle \rightleftharpoons }$ CoA + N-acetylphosphinothricin

The substrate phosphinothricin is used as a nonselective herbicide and is a potent inhibitor of EC 6.3.1.2.
