Sensor histidine kinase VxrA

UniProtKB accession:  Q9KM24

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Member of the two-component regulatory system VxrB/VxrA involved in the regulation of diverses processes, including virulence, the type VI secretion system (T6SS) and biofilm formation (PubMed:26000450, PubMed:28607158, PubMed:33753465). Functions 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 VxrB (By similarity). Is critical for colonization in the infant mouse model (PubMed:26000450). Contributes to the resistance to beta-lactam treatment (PubMed:33753465).
