1.3.7.4 | physiological function | plants utilize 3Z-phytochromobilin:ferredoxin oxidoreductase to reduce the diene system of the A ring of biliverdin IXalpha to form PthetaB | Arabidopsis thaliana |
1.3.7.5 | additional information | cyanobacteria utilize phycocyanobilin:ferredoxin oxidoreductase (PcyA) to perform a two-step reaction, the enzyme first reduces the 18-vinyl side chain of the D-ring and subsequently reduces the vinyl side chain of the pyrrole A ring to yield phycocyanobilin | Synechococcus sp. |
