The RCSB PDB also provides a variety of tools and resources. In anaerobic organisms, the decarboxylation of pyruvate, a crucial component of intermediary metabolism, is catalyzed by the metalloenzyme pyruvate: ferredoxin oxidoreductase (PFOR) resulting in the generation of low potential electrons and the subsequent acetylation of coenzyme A (CoA). These genes were absent in heliobacteria, cyanobacteria, algae, and plants; however, genomes of many green sulfur bacteria (especially marine ones) were found to contain the full rnf operon. 3-nitrotoluene dioxygenase (3NTDO) from Diaphorobacter sp.

It catalyzes the initial step in the aerobic degradation of toluene to cis-toluene dihydrodiol. Ferredoxin is a nucleus-encoded protein synthesized as a 126 amino-acid precursor which is processed to a 94 amino-acid mature protein. The alternative reaction (2) is written for a 2 [4Fe-4s] ferredoxin, which transfers two electrons, and occurs in metabolism of anaerobic bacteria. The 3 substrates of this enzyme are reduced ferredoxin, NADP +, and H +, whereas its two products are oxidized ferredoxin and NADPH.
