WebbSecondary structure: regular structural motifs formed by hydrogen bonding among atoms of the peptide backbone (i.e., motifs not directly involving the atoms of the amino acid side chains). Tertiary structure: the complete three-dimensional conformation of a … WebbIn proteins, the secondary structure is defined by patterns of hydrogen bonds between backbone amide and carboxyl groups (sidechain-mainchain and sidechain-sidechain hydrogen bonds are irrelevant), where the DSSP definition of a hydrogen bond is used.

New insights into protein-DNA binding specificity from hydrogen bond …

WebbThe secondary sphere is composed of residues that form mainly non-covalent interactions—hydrogen bonding, hydrophobic, and van der Waals (vDW) interactions—with the primary sphere. Although secondary sphere features do not directly bind the metal ion, they play an indispensable role in controlling metal-based reactivity. WebbIn addition to the hydrogen bonds between peptide bonds that gives rise to the secondary structure of the protein, hydrogen bonds can form between amino-acid side chains. Ionic bonding . The structure of a protein can be stabilized by the force of attraction between amino acid side chains of opposite charge, such as the -NH 3 + side chain of Leu and the … top rated auto body shops denver
