In enzymology an undecaprenyldiphospho-muramoylpentapeptide beta-N-acetylglucosaminyltransferase (EC 2.4.1.227) is an enzyme that catalyzes the chemical reactionUDP-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)- diphosphoundecaprenolThe 3 substrates of this enzyme are UDP-N-acetylglucosamine Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)- and diphosphoundecaprenol whereas its 3 products are UDP [[GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)-]] and diphosphoundecaprenol.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
