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...

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...

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

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...

significantly steeper than other helical packings such as the helix bundle. The exact angle of helix packing depends on the sequence of the protein, because...

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

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...
