Sysname
MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc:glycine glycyltransferase
Reaction(IUBMB)
MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc + 2 glycyl-tRNAGly = MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-tri-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc + 2 tRNAGly [RN:R08777]
Reaction(KEGG)
Substrate
MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc;
glycyl-tRNA(Gly) [CPD:C02412]
Product
MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-tri-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc;
tRNA(Gly) [CPD:C01642]
Comment
This enzyme catalyses the successive transfer of two Gly moieties from charged tRNAs to MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc, attaching them to a Gly residue previously attached by EC 2.3.2.16 (lipid II:glycine glycyltransferase) to the N6 of the L-Lys at position 3 of the pentapeptide. This is the second step in the synthesis of the pentaglycine interpeptide bridge that is used by Staphylococcus aureus for the crosslinking of different glycan strands to each other. The next step is catalysed by EC 2.3.2.18 (N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-(N6-triglycine)-D-alanyl-D-alanine-diphosphoundecaprenyl-N-acetylglucosamine:glycine glycyltransferase). This enzyme is essential for methicillin resistance [1].
