Type: | Domain | Name: | Fumarate reductase/succinate dehydrogenase flavoprotein-like, C-terminal |
Description: | This entry represents a domain with a spectrin-repeat-like fold consisting of three helices in a closed bundle with a left-handed twist. This domain is found in the succinate dehydrogenase/fumarate reductase oxidoreductase family of proteins, such as:L-aspartate oxidase (), a flavoenzyme component of the bacterial quinolinate synthase system that catalyses the conversion of L-aspartate to oxaloacetate, the first step in the de novo biosynthesis of NAD+ [, ].Fumarate reductase, which is part of the quinol-fumarate reductase (QFR) respiratory complex that catalyses the terminal step of anaerobic respiration when fumarate acts as the terminal electron acceptor [].Succinate dehydrogenase (SQR; ), an iron-sulphur flavoenzyme from bacteria that is analogous to the mitochondrial respiratory complex II, forming part of the electron transport pathway from the electron acceptor (succinate) to the terminal donor (ubiquinone) [].Adenylylsulphate reductase A subunit (), an iron-sulphur flavoenzyme that catalyses the reversible reduction of adenosine-5'-phosphate (APS) to sulphite and AMP []. | Short Name: | Fum_Rdtase/Succ_DH_flav-like_C |
