Homologous Superfamily

Electron transport accessory-like domain superfamily (IPR008990)

Short name: Elect_transpt_acc-like_dom_sf

Overlapping entries


The electron transport accessory proteins adopt the beta topology of an SH3 domain, with a partly opened beta barrel and a 3-10 helical turn interrupting the last strand. Other proteins displaying this topology include R67 dihydrofolate reductase, which catalyses the hydration of nitriles to amides [PMID: 9195885], photosystem I accessory proteins (PsaE), which participate in cyclic electron transport and modulate the interaction of photosystem I with ferrodoxin [PMID: 10521281], the alpha chain of ferrodoxin thioredoxin reductase (FTR), which is involved in the regulation of the activity of chloroplast enzymes [PMID: 10649999], and the beta chain of nitrile hydratase, which confers trimethoprim-resistance to R67-expressing bacteria [PMID: 12501195].
