Bacterial bifunctional deaminase-reductase, C-terminal (IPR002734)

Short name: RibDG_C

Overlapping homologous superfamilies

Domain relationships


This domain is found in the C terminus of the bifunctional deaminase-reductase of Escherichia coli, Bacillus subtilis and other bacteria in combination with IPR002125 that catalyses the second and third steps in the biosynthesis of riboflavin, i.e., the deamination of 2,5-diamino-6-ribosylamino-4(3H)-pyrimidinone 5'-phosphate (deaminase) and the subsequent reduction of the ribosyl side chain (reductase) [PMID: 9068650]. The domain is also present in some HTP reductases from archaea and fungi.
