peptidoglycan meso-diaminopimelic acid protein amidase DpaA (previously YafK and LdtF) murein L,D-transpeptidases, but actually functions as an amidase. In E. coli, the most abundant protein is the lipoprotein Lpp, anchored to the inner face of the outer membrane, but cross-linked to the peptidoglycan cell wall by the transpeptidases LdtA, LdtB, and LdtC. DpaA (peptidoglycan meso-diaminopimelic acid protein amidase A) is an amidase that hydrolyzes those linkages. |
