The chemical shift of an amide proton is sensitive to conformational variations, as well as to changes in the molecular ...
a在β折叠中,两条以上氨基酸链(肽链),或同一条肽链之间的不同部分形成平行或反平行排列,成为“股”。肽平面之间呈手风琴状折叠,股与股之间会通过氢键固定,但氢键主要在股间而不是股内。氨基酸残基的R侧链分布在片层的上下。 In beta the fold, two above amino acid chains (peptide chain), either between ...

23), suggesting that the two hydroxyl groups of Dopa residue can form H-bonds with both the side chain and the backbone. This extra hydrogen bond capacity enables Dopa to be a much stronger “sticker” than Tyr. With increased content of Dopa, more hydrogen bonds were observed between Dopa...
hydrogen bonds, coordinative bonds with metal ions, or metal oxide surfaces, π-π-electron interactions as well as cation-π interactions [38]. Contrary to physical immobilization, chemical immobilization is based on forming covalent bonds. Here, binding takes place using functional groups that are...

On the basis of our results, we found that the cooperativity of the hydrogen-bonded complexes become weaker as NH···OH2 and CO···HOH hydrogen bonds replacing NH···OC hydrogen bonds in protein and peptide. It means that the NH and CO bonds in peptide prefer to form NH···OC...
22and information about binding residues in peptides involved in hydrogen bonds and hydrophobic contacts. With the support from such supervised information, CAMP achieved an average AUC of 0.806 and Matthews Correlation Coefficient (MCC) (definitions can be found in Supplementary Note9) of 0.514 on ...
Secondary structures comprise a subset of amino acid sequences where each constituent residue forms hydrogen bonds (H-bonds) in specific orders with other constituent residues, at their peptidyl backbones, which grants a special mechanical property in our life-thriving nanomachines—proteins. Particularly...
