CC -!- FUNCTION: Member of the two-component regulatory system MprB/MprA which
CC contributes to maintaining a balance among several systems involved in
CC stress resistance and is required for establishment and maintenance of
CC persistent infection in the host. In response to environmental signals
CC MprB acts as both a membrane-associated protein kinase that undergoes
CC autophosphorylation and subsequently transfers the phosphate to MprA,
CC and a protein phosphatase that dephosphorylates phospho-MprA (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC histidine.; EC=2.7.13.3;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- PTM: Autophosphorylated. {ECO:0000250}.
