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}.
