PROCHECK statistics 1. Ramachandran Plot statistics No. of residues %-tage ------ ------ Most favoured regions [A,B,L] 253 93.7% Additional allowed regions [a,b,l,p] 17 6.3% Generously allowed regions [~a,~b,~l,~p] 0 0.0% Disallowed regions [XX] 0 0.0% ---- ------ Non-glycine and non-proline residues 270 100.0% End-residues (excl. Gly and Pro) 2 Glycine residues 34 Proline residues 15 ---- Total number of residues 321 Based on an analysis of 118 structures of resolution of at least 2.0 Angstroms and R-factor no greater than 20.0 a good quality model would be expected to have over 90% in the most favoured regions [A,B,L]. 2. G-Factors Average Parameter Score Score --------- ----- ----- Dihedral angles:- Phi-psi distribution -0.01 Chi1-chi2 distribution -0.12 Chi1 only 0.06 Chi3 & chi4 0.36 Omega 0.44 0.16 ===== Main-chain covalent forces:- Main-chain bond lengths 0.52 Main-chain bond angles 0.29 0.39 ===== OVERALL AVERAGE 0.26 ===== G-factors provide a measure of how unusual, or out-of-the-ordinary, a property is. Values below -0.5* - unusual Values below -1.0** - highly unusual Important note: The main-chain bond-lengths and bond angles are compared with the Engh & Huber (1991) ideal values derived from small-molecule data. Therefore, structures refined using different restraints may show apparently large deviations from normality.
