Protein

Aminoacyltransferase FemA

Gene

femA

Organism
Staphylococcus aureus
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the formation of the pentaglycine interpeptide bridge, which is characteristic of the S.aureus peptidoglycan. Adds glycines 2 and 3 of the pentaglycine bridge, using glycyl-tRNA(Gly) as donor.

Miscellaneous

Since cross-linking between the peptide strands is critical for maintaining stability of the cell wall, FemA is a potential target for the development of new antibacterial agents.

Catalytic activityi

MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc + 2 glycyl-tRNA = MurNAc-L-Ala-D-isoglutaminyl-L-Lys-(N6-tri-Gly)-D-Ala-D-Ala-diphospho-ditrans,octacis-undecaprenyl-GlcNAc + 2 tRNA.
