Method: X-ray diffraction, Resolution 2.715Å Ligands: CA Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function SIDJ_LEGPH Glutamylase that mediates the covalent attachment of glutamate moieties to SdeA on one of the catalytic residues that is required for its mono-ADP-ribosyltransferase activity (PubMed:31330532, PubMed:31330531). In turn, inhibits SdeA ubiquitinating activity. Glutamylates also related SdeB, SdeC and SidE (PubMed:31330531, PubMed:31123136). Glutamylase activity only occurs in the host since it requires host calmodulin (PubMed:28497808, PubMed:31330532, PubMed:31330531, PubMed:31123136). May also reverse the SdeA-mediated substrate ubiquitination by cleaving the phosphodiester bond that links phosphoribosylated ubiquitin to protein substrates via its deubiquitinase activity (PubMed:28497808).
