Microbiol. 9:401. doi: … WebIn order to produce such reduction, this enzyme receives electrons from a [2Fe–2S] plant-type ferredoxin (Fd), which is previously reduced by PS I. Moreover, in the case of some algae and cyanobacteria, an FMN-dependent protein, flavodoxin (Fld), has been shown to replace Fd in this function.
