Nativelike Structure in Designed Four α-Helix Bundles …
Four-helix bundles typically consist of four helices packed in a coiled-coil arrangement with a sterically close-packed hydrophobic core in the center. Pairs of adjacent helices are often additionally stabilized by salt bridges between charged amino acids. The helix axes typically are oriented about 20 degrees … Visa mer A helix bundle is a small protein fold composed of several alpha helices that are usually nearly parallel or antiparallel to each other. Visa mer Three-helix bundles are among the smallest and fastest known cooperatively folding structural domains. The three-helix bundle in the villin headpiece domain is only 36 amino acids long and is a common subject of study in molecular dynamics simulations because its Visa mer • Knobs into holes packing Visa mer • SCOP cytochrome c fold • SCOP nucleic acid-binding three-helix bundles • SCOP four-helix bundles Visa mer Webbrestrictions, there are 4 residues per turn in the models considered here. Moreover, in real proteins, the helices are slightly tilted with respect to each other, and the four-helix … Webb26 aug. 2015 · A four-helix bundle is formed upon Cu (I) addition to a synthetic peptide possessing a CXXC motif, and binds a Cu 4 S 4 cluster 28.
