Here, hundreds of separate types of enzymes remove electrons from their substrates and reduce NAD + to NADH . This reduced cofactor is then a substrate for any of the reductases in the cell that require electrons to reduce their substrates.

Unlike many other " Shewanella " species, " S . violacea " has very few terminal reductases for anaerobic respiration, c-type cytocromes and no Fe ( iii ) reduction outer membrane proteins involved in respiration.

The enzymes include ferredoxin-NADP + reductases, plant and fungal NAD ( P ) H : nitrate reductases, cytochrome b5 reductases, cytochrome P450 reductases, sulphite reductases, nitric oxide synthases, phthalate dioxygenase reductase, and various other flavoproteins.

Selenocysteine is present in several enzymes ( for example glutathione peroxidases, tetraiodothyronine 5'deiodinases, thioredoxin reductases, formate dehydrogenases, glycine reductases, selenophosphate synthetase 2, methionine-R-sulfoxide reductase B1 ( SEPX1 ), and some hydrogenases ).

One of the most notable group of proteins whose functional diversification appears to have been heavily influenced by such an evolutionary mechanism is the ferritin-like superfamily, which includes ferritins, bacterioferritins, rubrerythrins, class I ribonucleotide reductases and soluble methane monooxygenases.
