| Primary Identifier | IPR029012 | Type | Homologous_superfamily |
| Short Name | Helix_hairpin_bin_sf |
| description | 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 α-helices. A four-residue linker between the helices allows them to form an anti-parallel bundle and cross over each other towards their termini []. A similar domain is found in Sulfolobus spindle-shaped virus 1 (SSV1) protein D-63 []. This domain is also present in eukaryotic proteins such as Golgi to ER traffic protein 1 (GET1), also known as tail-anchored protein insertion receptor WRB, Pre-mRNA-splicing factor ISY1 and Vacuolar protein sorting-associated protein 37. |
