Oxygen sensor histidine kinase response regulator DosT

UniProtKB accession:  P9WGK1

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Interacts with the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Required for full induction of the DevR (DosR) regulon; required during early adaptation to anaerobiosis, to start induction of the DevR regulon (PubMed:19487478). May act as a direct hypoxia/oxygen sensor (PubMed:17609369, PubMed:17600145, PubMed:28977726). O(2) acts as a switch, with the Fe(2+)-O(2)-bound protein inactive in autophosphorylation (PubMed:17600145). Autophosphorylates under anaerobic but not aerobic conditions, binding of NO or CO has no effect on autophosphorylation (PubMed:17600145). Binds a number of gases; O(2), NO, CO (PubMed:17609369, PubMed:17600145). May be a secondary sensor for CO (PubMed:18400743). Donates a phosphate group to transcriptional regulator DevR (DosR) (PubMed:15135056, PubMed:15033981, PubMed:28977726).
