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       (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-D-isoglutaminyl-L-Lys-D-
CC         Ala-D-Ala)-di-trans,octa-cis-undecaprenyl diphosphate + glycyl-
CC         tRNA(Gly) = beta-D-GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-D-isoglutaminyl-L-
CC         Lys-(N(6)-Gly)-D-Ala-D-Ala)-di-trans,octa-cis-undecaprenyl
CC         diphosphate + H(+) + tRNA(Gly); Xref=Rhea:RHEA:30435, Rhea:RHEA-
CC         COMP:9664, Rhea:RHEA-COMP:9683, ChEBI:CHEBI:15378, ChEBI:CHEBI:62233,
CC         ChEBI:CHEBI:62234, ChEBI:CHEBI:78442, ChEBI:CHEBI:78522; EC=2.3.2.16;
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the FemABX family. {ECO:0000305}.
