WebThe figure below shows the three main chain torsion angles of a polypeptide. Phi (Φ; C, N, C α, C) and psi (Ψ; N, C α, C, N) are on either side of the C α atom and omega (ω; C α, C, N, C α) describes the angle of the peptide bond. While Φ and Ψ have considerable rotational freedom, ω is planar. This is a result of the partial double ...

WebBiochem/physiol Actions. Polyglycine exists in two forms, namely the polyglycine I (PGI) with anti-parallel β-sheet structure and polyglycine II (PGII) with extended 31-helix. It is a most flexible polypeptide with minimal steric hindrance and its solubility increases in the presence of lithium ions. [ 3] It is present in mammals and plants. WebCis and Trans Peptide Bonds: Two possible orientations of the peptide bond that maintain a favorable \(p_z\)interaction between the carbon and nitrogen are possible. They are related by a 180\(^{\circ}\) flip of the peptide bond, generating the trans form and the cis form. For all peptide bonds, the trans form is more stable than the cis form.

WebThe most common way of linking such protein or peptide domains is by inclusion of a flexible linker. These linkers are commonly glycine-rich, for example solely glycine residues (G), or glycine residues interspersed with serine residues (GS) to form repeating sequences. This provides the linker with enough flexibility as not to interfere with ...
