A	UDP-N-acetylmuramoylpentapeptide-lysine N6-alanyltransferase M-CSA #781	FemX uses aminoacyl-tRNA as an amino acid donor to synthesise the peptide cross-bridge in peptidoglycan, apart of the cell wall of gram-positive bacteria. FemX belongs to the Fem family of nonribosomal peptidyl transferases . FemX is required for cell survival and is a target for beta-lactam antibiotics.
