CC   -!- FUNCTION: Catalyzes the incorporation of the first glycine of the
CC       pentaglycine interpeptide bridge, which is characteristic of the
CC       S.aureus peptidoglycan. This glycine is added to the epsilon-amino
CC       group of the L-lysine of the membrane-bound lipid II intermediate
CC       (GlcNAc-(beta-1,4)-N-acetylmuramic acid(-L-Ala-D-iGln-L-Lys-D-Ala-D-
CC       Ala)-pyrophosphoryl-undecaprenol), using glycyl-tRNA(Gly) as donor, in
CC       a ribosome-independent mechanism. Involved in methicillin resistance.
CC       {ECO:0000269|PubMed:15280360}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-D-isoglutaminyl-L-Lys-D-
