CC -!- FUNCTION: Transpeptidase that cleaves the poly-gamma-D-glutamate
CC capsule and catalyzes the formation of an amide bond with the side-
CC chain amino group of meso-diaminopimelic acid (m-DAP) in the
CC peptidoglycan scaffold (PubMed:19017271). Degradation of the high-
CC molecular weight capsule (H-capsule) to the lower-molecular weight
CC capsule (L-capsule), which is released from the bacterial cell surface.
CC The production of L-capsule is essential to mediate escape from host
CC defenses. {ECO:0000269|PubMed:12134259, ECO:0000269|PubMed:19017271,
CC ECO:0000269|PubMed:19535342, ECO:0000269|PubMed:8105361}.
CC -!- PATHWAY: Capsule biogenesis; capsule polysaccharide biosynthesis.
CC -!- SUBUNIT: This enzyme consists of two polypeptide chains, which are
CC synthesized in precursor form from a single polypeptide.
CC {ECO:0000269|PubMed:19535342}.
CC -!- INDUCTION: Capsule synthesis is transcriptionally regulated by AtxA,
CC AcpA and AcpB. {ECO:0000269|PubMed:14702298}.
CC -!- PTM: Cleaved by autocatalysis into a large and a small subunit.
CC -!- SIMILARITY: Belongs to the gamma-glutamyltransferase family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAF13660.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
CC Sequence=BAA03126.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
