EKR is a short, 33 residue, domain found in bacterial and some lower eukaryotic species which lies between a POR (pyruvate ferredoxin/flavodoxin oxidoreductase) Pfam:PF01558 and the 4Fe-4S binding domain Fer4 Pfam:PF00037. It contains a characteristic EKR sequence motif. The exact function of this domain is not known. (from Pfam)

This family includes the N terminal structural domain of the pyruvate ferredoxin oxidoreductase. This domain binds thiamine diphosphate, and along with domains II and IV, is involved in inter subunit contacts [3]. The family also includes pyruvate flavodoxin oxidoreductase as encoded by the nifJ gene in cyanobacterium which is required for growth on molecular nitrogen when iron is limited [2]. [1]. 8550425.

This family includes a region of the large protein pyruvate-flavodoxin oxidoreductase and the whole pyruvate ferredoxin oxidoreductase gamma subunit protein. It is not known whether the gamma subunit has a catalytic or regulatory role. Pyruvate oxidoreductase (POR) catalyses the final step in the fermentation of carbohydrates in anaerobic microorganisms [1]. This involves the oxidative decarboxylation of pyruvate with the participation of thiamine followed by the transfer of an acetyl moiety to coenzyme A for the synthesis of acetyl-CoA [1]. The family also includes pyruvate flavodoxin oxidoreductase as encoded by the nifJ gene in cyanobacterium which is required for growth on molecular nitrogen when iron is limited [2]. [1]. 8550425.
