>TIGR02016 BchX chlorophyllide reductase iron protein subunit X; InterPro: IPR010246 This entry represents the X subunit of the three-subunit enzyme, (bacterio)chlorophyllide reductase , . This enzyme is responsible for the reduction of the chlorin B-ring and is closely related to the protochlorophyllide reductase complex which reduces the D-ring. Both of these complexes in turn are homologous to nitrogenase. This subunit is homologous to the nitrogenase component II, or 'iron' protein.; GO: 0005524 ATP binding, 0016628 oxidoreductase activity acting on the CH-CH group of donors NAD or NADP as acceptor, 0051539 4 iron 4 sulfur cluster binding, 0015979 photosynthesis, 0030494 bacteriochlorophyll biosynthetic process.
