- N-acetylmuramoyl-L-alanyl-D-isoglutaminyl-L-lysyl-(N6-glycyl)-D-alanyl-D-alanine-diphospho-ditrans,octacis-undecaprenyl-N-acetylglucosamine + 2 glycyl-tRNA N-acetylmuramoyl-L-alanyl-D-isoglutaminyl-L-lysyl-(N6-triglycyl)-D-alanyl-D-alanine-diphospho-ditrans,octacis-undecaprenyl-N-acetylglucosamine + 2 tRNA
This enzyme catalyses the successive transfer of two glycine moieties from charged tRNAs to N-acetylmuramoyl-L-alanyl-D-isoglutaminyl-L-lysyl-(N6-glycyl)-D-alanyl-D-alanine-diphosphoundecaprenyl-N-acetylglucosamine.
