Transcriptional regulatory protein ZraR

UniProtKB accession:  P25852

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Part of the Zra signaling pathway, an envelope stress response (ESR) system composed of the periplasmic accessory protein ZraP, the histidine kinase ZraS and the transcriptional regulator ZraR (PubMed:22084975). The ZraPSR system contributes to antibiotic resistance and is important for membrane integrity in the presence of membrane-targeting biocides (By similarity). ZraR is a member of the two-component regulatory system ZraS/ZraR (PubMed:22084975). When activated by ZraS, acts in conjunction with sigma-54 to regulate the expression of zraP in the presence of high Zn(2+) or Pb(2+) concentrations (By similarity). Also positively autoregulates the expression of the zraSR operon (By similarity).
