Homologous Superfamily

Arc-type ribbon-helix-helix (IPR013321)

Short name: Arc_rbn_hlx_hlx

Overlapping entries


This superfamily represents a domain with a ribbon-helix-helix topology consisting of four helices in an open array of two hairpins. This domain is found in Mnt and Arc, two structurally homologous repressors encoded by bacteriophage P22 [PMID: 7999761, PMID: 12646376]. This entry also includes nickel-responsive regulator [PMID: 16945905] and protein CopG [PMID: 9857196].
