Capsule biosynthesis protein CapD proenzyme

UniProtKB accession:  Q51693

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Transpeptidase that cleaves the poly-gamma-D-glutamate capsule and catalyzes the formation of an amide bond with the side-chain amino group of meso-diaminopimelic acid (m-DAP) in the peptidoglycan scaffold (PubMed:19017271). Degradation of the high-molecular weight capsule (H-capsule) to the lower-molecular weight capsule (L-capsule), which is released from the bacterial cell surface. The production of L-capsule is essential to mediate escape from host defenses.
