Competition between Different Pathways for Photosynthetic Reductants

4 Competition between Different Pathways for Photosynthetic Reduct ants 

A key intermediate electron transport carrier on the reducing side of PSI in green algae and cyanobacteria is the FeS-containing ferredoxin (see Fd in Fig. 1). Ferre-doxin is a soluble protein that competitively interacts with an array of different enzymes (cf. Ref. 128 and references therein) including  

Based on the homology of the cyanobacterial bidirectional hydrogenase with the NAD+-reducing hydrogenase from R. eutropha and the detection of NAD+-reducing activity from H2 oxidation (described in Section 3.2), cyanobacterial H2
