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.4 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
