N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-(N6-triglycine)-D-alanyl-D-alanine-diphosphoundecaprenyl-N-acetylglucosamine:glycine glycyltransferase (EC 2.3.2.18, femB (gene)) is an enzyme with systematic name N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-(N6-triglycine)-D-alanyl-D-alanine-ditrans,octacis-diphosphoundecaprenyl-N-acetylglucosamine:glycine glycyltransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- N-acetylmuramoyl-L-alanyl-D-isoglutaminyl-L-lysyl-(N6-triglycyl)-D-alanyl-D-alanine-diphospho-ditrans,octacis-undecaprenyl-N-acetylglucosamine + 2 glycyl-tRNA [math]\displaystyle{ \rightleftharpoons }[/math] N-acetylmuramoyl-L-alanyl-D-isoglutaminyl-L-lysyl-(N6-pentaglycyl)-D-alanyl-D-alanine-diphospho-ditrans,octacis-undecaprenyl-N-acetylglucosamine + 2 tRNA
This Staphylococcus aureus enzyme catalyses the successive transfer of two glycine moieties from charged tRNAs to N-acetylmuramoyl-L-alanyl-D-isoglutaminyl-L-lysyl-(N6-triglycyl)-D-alanyl-D-alanine-diphosphoundecaprenyl-N-acetylglucosamine.
