HHsearch alignment for GI: 254780332 and conserved domain: cd02040
>cd02040 NifH NifH gene encodes component II (iron protein) of nitrogenase. Nitrogenase is responsible for the biological nitrogen fixation, i.e. reduction of molecular nitrogen to ammonia. NifH consists of two oxygen-sensitive metallosulfur proteins: the mollybdenum-iron (alternatively, vanadium-iron or iron-iron) protein (commonly referred to as component 1), and the iron protein (commonly referred to as component 2). The iron protein is a homodimer, with an Fe4S4 cluster bound between the subunits and two ATP-binding domains. It supplies energy by ATP hydrolysis, and transfers electrons from reduced ferredoxin or flavodoxin to component 1 for the reduction of molecular nitrogen to ammonia.
