OX NCBI_TaxID=1574623 {ECO:0000313|EMBL:KIF42405.1, ECO:0000313|Proteomes:UP000031561}; RN [1] {ECO:0000313|EMBL:KIF42405.1, ECO:0000313|Proteomes:UP000031561} RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=BDU141951 {ECO:0000313|EMBL:KIF42405.1, RC ECO:0000313|Proteomes:UP000031561}; RA Malar M.C., Sen D., Tripathy S.; RT "Draft genome sequence of Lyngbya confervoides BDU141951."; RL Submitted (NOV-2014) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Involved in the modulation of the chemotaxis system; CC catalyzes the demethylation of specific methylglutamate residues CC introduced into the chemoreceptors (methyl-accepting chemotaxis CC proteins) by CheR. {ECO:0000256|HAMAP-Rule:MF_00099, CC ECO:0000256|SAAS:SAAS00407323}. CC -!- CATALYTIC ACTIVITY: Protein L-glutamate O(5)-methyl ester + H(2)O CC = protein L-glutamate + methanol. {ECO:0000256|HAMAP- CC Rule:MF_00099, ECO:0000256|SAAS:SAAS00706688}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00099, CC ECO:0000256|SAAS:SAAS00407336}. CC -!- DOMAIN: The N-terminal regulatory domain inhibits the activity of CC the C-terminal effector domain. {ECO:0000256|HAMAP-Rule:MF_00099}. CC -!- PTM: Phosphorylated by CheA. Phosphorylation suppresses the CC inhibitory activity of the N-terminal domain. {ECO:0000256|HAMAP- CC Rule:MF_00099}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:KIF42405.1}.
