Domain

NADH:flavin oxidoreductase/NADH oxidase, N-terminal (IPR001155)

Short name: OxRdtase_FMN_N

Domain relationships

None.

Description

The TIM-barrel fold is a closed barrel structure composed of an eight-fold repeat of beta-alpha units, where the eight parallel beta strands on the inside are covered by the eight alpha helices on the outside [PMID: 11257493]. It is a widely distributed fold which has been found in many enzyme families that catalyse completely unrelated reactions [PMID: 12206759]. The active site is always found at the C-terminal end of this domain.

Proteins in this entry are a variety of NADH:flavin oxidoreductase/NADH oxidase enzymes, found mostly in bacteria or fungi, that contain a TIM-barrel fold. They commonly use FMN/FAD as cofactor and include:

  • dimethylamine dehydrogenase
  • trimethylamine dehydrogenase
  • 12-oxophytodienoate reductase
  • NADPH dehydrogenase
  • NADH oxidase
