Domain

Pyruvate-flavodoxin oxidoreductase, central domain (IPR002869)

Short name: Pyrv_flavodox_OxRed_cen

Domain relationships

None.

Description

This domain is found in prokaryotes. It 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 [PMID: 8550425]. 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 [PMID: 8550425]. 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 [PMID: 8415612].
