In enzymology, a phospho-N-acetylmuramoyl-pentapeptide-transferase (EC 2.7.8.13) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are UDP-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala) and undecaprenyl phosphate, whereas its 2 products are UMP and Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)-diphosphoundecaprenol.
This enzyme participates in peptidoglycan biosynthesis. It can be expressed efficiently by a cell-free protein expression system.
