CC -!- FUNCTION: Interacts with the two-component regulatory system DevR/DevS
CC (DosR/DosS) involved in onset of the dormancy response. Required for
CC full induction of the DevR (DosR) regulon; required during early
CC adaptation to anaerobiosis, to start induction of the DevR regulon (By
CC similarity). May act as a direct hypoxia/oxygen sensor (By similarity).
CC May be the secondary sensor for CO (By similarity). Donates a phosphate
CC group to DevR (DosR) (By similarity). {ECO:0000250|UniProtKB:P9WGK1}.
