HHsearch alignment for GI: 254780655 and conserved domain: cd03375

>cd03375 TPP_OGFOR Thiamine pyrophosphate (TPP family), 2-oxoglutarate ferredoxin oxidoreductase (OGFOR) subfamily, TPP-binding module; OGFOR catalyzes the oxidative decarboxylation of 2-oxo-acids, with ferredoxin acting as an electron acceptor. In the TCA cycle, OGFOR catalyzes the oxidative decarboxylation of 2-oxoglutarate to succinyl-CoA. In the reductive tricarboxylic acid cycle found in the anaerobic autotroph Hydrogenobacter thermophilus, OGFOR catalyzes the reductive carboxylation of succinyl-CoA to produce 2-oxoglutarate. Thauera aromatica OGFOR has been shown to provide reduced ferredoxin to benzoyl-CoA reductase, a key enzyme in the anaerobic metabolism of aromatic compounds. OGFOR is dependent on TPP and a divalent metal cation for activity.
