CC   -!- FUNCTION: Member of the two-component regulatory system HptS/HptR that
CC       regulates genes involved in hexose phosphate transport system in
CC       response to changes in extracellular phosphate sources. Activates uhpT
CC       expression to facilitate glucose-6-phosphate/G6P utilization by
CC       directly binding to its promoter. Antagonizes CcpA-dependent
CC       transcription of a subset of CcpA-regulated genes involved in
CC       antibiotic susceptibility. {ECO:0000250|UniProtKB:Q2G1E1}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- PTM: Phosphorylated by HptS. {ECO:0000250|UniProtKB:Q2G1E1}.
