Collagen protein structure secondary
WebThe secondary structure is assigned based on hydrogen bonding patterns as those initially proposed by Pauling et al. in 1951 (before any protein structure had ever been experimentally determined). There are eight types of secondary structure that DSSP defines: G = 3-turn helix ( 3 10 helix ). Min length 3 residues. H = 4-turn helix ( α helix ). WebJan 31, 2024 · Secondary structure is the repetitive structure formed from H-bonds among backbone amide H and carbonyl O atoms. Tertiary structure is the overall 3D structure of the protein.
