WebAn antimicrobial peptide, known as V13K, was utilized as the framework to study the effects of charge, hydrophobicity and helicity on the biophysical properties and biological activities of α-helical peptides. Six amino acids (Lys, Glu, Gly, Ser, Ala, and Leu) were individually used to substitute the original hydrophobic valine at the selected sixteenth location on … WebAug 29, 2006 · For example, a lysine side chain contains four methylenes, which may undergo hydrophobic interactions if the charged ε-NH3+group is salt-bridged or hydrogen-bonded. Folding initiation sites might therefore contain not only accepted “hydrophobic” amino acids, but also larger charged side chains. inala shoes

WebConsistent with other coiled coils 3, all ten residues at positions a and d are appropriately aligned for burying hydrophobic side chains away from the water solvent. This confers a major energy contribution to dimerisation 28, with interatomic distances consistent with important structure-stabilising interhelical a-a’ and d-d’ interactions ... WebSep 27, 2002 · Our results have major implications to understanding the influence of hydrophobic and aqueous environment on hydrophilicity/hydrophobicity of amino acid side-chains and the role side-chains play in the folding and stability of proteins.
