Protein
N(2)-fixation sustaining protein CowN
Organism
Rhodospirillum rubrum (strain ATCC 11170 / ATH 1.1.1 / DSM 467 / LMG 4362 / NCIB 8255 / S1)
Function
Is required to sustain N(2)-dependent growth in the presence of low levels of carbon monoxide (CO). Probably acts by protecting the N(2) fixation ability of the nitrogenase complex, which is inactivated in the presence of CO. Is not required for CO-dependent growth.
Similarity
Belongs to the CowN family.
