In conclusion, we would like to emphasize two points: first, the importance of the cis conformation of peptide bonds in protein structures, especially if it is a Xaa–nonPro peptide bond ...

A peptide bond is an amide type of covalent chemical bond linking two consecutive alpha-amino acids from C1 (carbon number one) of one alpha-amino acid and N2 (nitrogen number two) of another, along a ...

A 13-residue peptide from nNOS is bound to the ... as part of the pH sensitive monomer–dimer switch. The structure shows a hydrogen bond from His 55 NεH to Thr 67' C=O. At higher pH values ...

A peptide bond is a covalent bond that forms between the carboxyl group of one amino acid ... The sequence of amino acids in a protein, known as its primary structure, determines its unique ...

Over the past 25 years, Raines' lab has been studying collagen and how its structure enables its function. In the new study, they revealed why the peptide bonds that hold collagen together are so ...
