Sensor protein kinase HptS

UniProtKB accession:  Q2G1E0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Member of the two-component regulatory system HptS/HptR that regulates genes involved in hexose phosphate transport system in response to changes in extracellular phosphate sources (PubMed:25644013). May act as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of HptS. In turn, HptS antagonizes CcpA-dependent transcription of a subset of CcpA-regulated genes involved in antibiotic susceptibility (PubMed:30540769).
