CC   -!- FUNCTION: Member of the two-component regulatory system PprA/PprB
CC       involved in biofilm formation by controlling the expression of many
CC       related genes including type IVb pili major subunit flp pilin, adhesin
CC       bapA or cupE fimbriae. Modulates also quorum-sensing signal production
CC       acting on both negative and positive modulators. Functions as a heme
CC       sensor histidine kinase which is autophosphorylated at a histidine
CC       residue and transfers its phosphate group to PprB.
CC       {ECO:0000250|UniProtKB:Q9HWA7}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC         histidine.; EC=2.7.13.3; Evidence={ECO:0000250|UniProtKB:Q99SZ7};
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- PTM: Autophosphorylated on His-156. {ECO:0000250|UniProtKB:Q99SZ7}.
