Aslfm, the D-Aspartate Ligase Responsible for the Addition of D-Aspartic Acid onto the Peptidoglycan Precursor of Enterococcus faecium

D-aspartate ligase has remained the last unidentified peptide bond-forming enzyme in the peptidoglycan assembly pathway of Gram-positive bacteria. Here we show that a two-gene cluster of Enterococcus faecium encodes aspartate racemase (Racfm) and ligase (Aslfm) for incorporation of D-Asp into the si... View More
