CC -!- FUNCTION: Member of the two-component regulatory system UvrY/BarA
CC involved in the regulation of carbon metabolism via the CsrA/CsrB
CC regulatory system. Phosphorylates UvrY, probably via a four-step
CC phosphorelay (By 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 -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- PTM: Activation requires a sequential transfer of a phosphate group
CC from a His in the primary transmitter domain, to an Asp in the receiver
CC domain and to a His in the secondary transmitter domain. {ECO:0000250}.
