Abstract: The FemABX family encodes enzymes that incorporate L-amino acids into the interchain peptide bridge of Gram-positive cell wall peptidoglycan and are novel nonribosomal peptidyl transferases that use aminoacyltRNA as the amino acid donor. We previously reported the identification of the femX gene from The ⑀-NH 2 group of diamino acids such as meso-diaminopimelic acid, L-lysine, or L-ornithine of the stem peptide of peptidoglycan is cross-linked to D-Ala 4 of the neighboring peptide either directly or via inter…
