Enzyme Information

2.4.1.227

Undecaprenyldiphospho-muramoylpentapeptide beta-N- acetylglucosaminyltransferase.

based on mapping to UniProt Q9HW01

UDP-N-acetylglucosamine + Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D- Ala)-diphosphoundecaprenol = UDP + GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma- D-Glu-L-Lys-D-Ala-D-Ala)-diphosphoundecaprenol.

-!- The enzyme also works when the lysine residue is replaced by meso- 2,6-diaminoheptanedioate (meso-2,6-diaminopimelate, A2pm) combined with adjacent residues through its L-center, as it is in Gram- negative and some Gram-positive organisms. -!- The undecaprenol involved is ditrans,octacis-undecaprenol.
