General Information

General Information Comment Organism
metabolism bacteriochlorophyll a (BChl) is an essential pigment for anoxygenic photosynthesis. In late steps of the BChl biosynthesis, the C8 vinyl group and C7=C8 double bond of 8-vinyl chlorophyllide a (8 V-Chlide) are reduced by a C8 vinyl reductase (8VR), BciA (EC 1.3.1.75) or BciB and a nitrogenase-like enzyme, chlorophyllide a oxidoreductase (COR, EC 1.3.7.15), respectively, to produce 3-vinyl-bacteriochlorphyllide a Chloroherpeton thalassium
physiological function bacteriochlorophyll a (BChl) is an essential pigment for anoxygenic photosynthesis. In late steps of the BChl biosynthesis, the C8 vinyl group and C7=C8 double bond of 8-vinyl chlorophyllide a (8 V-Chlide) are reduced by a C8 vinyl reductase (8VR), BciA (EC 1.3.1.75) or BciB, and a nitrogenase-like enzyme, chlorophyllide a oxidoreductase (COR), respectively, to produce 3-vinyl-bacteriochlorphyllide a. BciB is a FAD-containing FeS protein that uses reduced ferredoxin as the reductant for the 8-vinyl reduction of 8 V-Chlide or 8 V-PChlide, while BciA utilizes NADPH. BciB is a FAD-containing FeS protein that uses reduced ferredoxin as the reductant for the 8-vinyl reduction of 8 V-Chlide or 8 V-PChlide Chloroherpeton thalassium
