CC   -!- FUNCTION: Catalyzes the formation of the pentaglycine interpeptide
CC       bridge, which is characteristic of the S.aureus peptidoglycan. Adds
CC       glycines 4 and 5 of the pentaglycine bridge, using glycyl-tRNA(Gly) as
CC       donor. Involved in resistance to methicillin (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 glycyl-tRNA(Gly) + MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N(6)-
CC         tri-Gly)-D-Ala-D-Ala-diphospho-di-trans,octa-cis-undecaprenyl-GlcNAc
CC         = 2 H(+) + MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N(6)-penta-Gly)-D-Ala-

CC   -!- SUBUNIT: Homodimer. Interacts with FemA (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the FemABX family. {ECO:0000305}.
