A helix bundle is a small protein fold composed of several alpha helices that are usually nearly parallel or antiparallel to each other. Three-helix bundles...

An alpha helix (or α-helix) is a sequence of amino acids in a protein that are twisted into a coil (a helix). The alpha helix is the most common structural...

{\displaystyle \alpha } -helix bundle, where one α {\displaystyle \alpha } -helix is contributed by syntaxin 1, one α {\displaystyle \alpha } -helix by synaptobrevin...

Structurally, Rop is a homodimeric four-helix bundle protein formed by the antiparallel interaction of two helix-turn-helix monomers. The Rop protein's structure...

of a helix hairpin is unknown; however, a four helix bundle is composed of two helix hairpins, which have important ligand binding sites. A helix corner...

composed of five homologous Ig-binding domains that fold into a three-helix bundle. Each domain is able to bind proteins from many mammalian species, most...

crystallize bHLH proteins bound to E-boxes, demonstrating that the parallel 4-helix bundle motif loop orients the basic sequences to interact with specific nucleotides...

major capsid protein (MCP) that contains the SIRV2 fold, a type of alpha-helix bundle containing four helices. The virion consists of the genome encased in...

the C-terminus consisting of a fast and independently folding three-helix bundle that is stabilized by hydrophobic interactions. The headpiece domain...

parallel 4 helix bundle. This bundle marks the BamHI dimer interface, and it is thought that the dipole moments of the NH2-terminal atoms on this bundle may...
