Homologous Superfamily

Globular protein, non-globular alpha/beta subunit (IPR011070)

Short name: Globular_prot_asu/bsu

Overlapping entries


Certain globular proteins from different functional families contain non-globular alpha+beta subunits. These proteins do not form a true superfamily, but share a similar topology in their non-globular subunits. Proteins that display this structure include phycoerythrin 545 alpha subunits (IPR004228), which are light-harvesting biliproteins found in cryptomonads [PMID: 9425063], the chaperone-binding domain of the virulence effector SptP from Salmonella typhimurium, which acts to modulate host cellular responses [PMID: 11689946], and the ubiquinol-cytochrome c reductase 8kDa protein (EC:, an integral membrane protein complex essential to cellular respiration [PMID: 12269811].
