CC   -!- FUNCTION: Is required to sustain N(2)-dependent growth in the presence
CC       of low levels of carbon monoxide (CO). Probably acts by protecting the
CC       N(2) fixation ability of the nitrogenase complex, which is inactivated
CC       in the presence of CO. {ECO:0000255|HAMAP-Rule:MF_02117}.
CC   -!- SIMILARITY: Belongs to the CowN family. {ECO:0000255|HAMAP-
CC       Rule:MF_02117}.
