Figure 3From: ROTAS: a rotamer-dependent, atomic statistical potential for assessment and prediction of protein structuresSchematic representation of residue flexibility and rotameric state. (A) Ball-stick representation of Asn which has two side-chain dihedral angles. (B) Newman diagram of three favored X1 angles in proteins. The −60, +60, and 180 angles are often referred to as gauche minus (g-), gauche plus (g+), and trans (t), respectively.Back to article page
