Homologous Superfamily

Helix hairpin bin domain superfamily (IPR029012)

Short name: Helix_hairpin_bin_sf

Overlapping entries


This domain superfamily is found in uncharacterised protein whose genomic location within nitrogen fixation clusters suggests that they may play a role in this process. They consist of two alpha-helices. A four-residue linker between the helices allows them to form an anti-parallel bundle and cross over each other towards their termini [PMID: 19336042]. A similar domain is found in Sulfolobus spindle-shaped virus 1 (SSV1) protein D-63 [PMID: 15220417].
