Photosynthetic apparatus regulatory protein RegA

Gene

regA

Organism
Rhodobacter sphaeroides (strain ATCC 17023 / 2.4.1 / NCIB 8253 / DSM 158)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Member of the two-component regulatory system RegB/RegA. Involved in transactivating anaerobic expression of the photosynthetic apparatus. It is a transcriptional regulator that is responsible for activating expression of the puf, puh, and puc operons in response to a decrease in oxygen tension.
