?cl00659: FdhD-NarQ Superfamily (this model, PSSM-Id:412501 is obsolete and has been replaced by 469863)
FdhD/NarQ family A pan-bacterial lineage of proteins. Nitrate assimilation protein, NarQ, and FdhD are required for formate dehydrogenase activity. Structurally, they possess a deaminase fold with a characteristic binding pocket, suggesting that they might bind a nucleotide or related molecule allosterically to regulate the formate dehydrogenase catalytic subunit.
