PROCHECK summary for 3cpw
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 2673 85.2%*
Additional allowed regions [a,b,l,p] 426 13.6%
Generously allowed regions [~a,~b,~l,~p] 26 0.8%
Disallowed regions [XX] 12 0.4%*
---- ------
Non-glycine and non-proline residues 3137 100.0%
End-residues (excl. Gly and Pro) 56
Glycine residues 340
Proline residues 172
----
Total number of residues 3705
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 -0.42
Chi1-chi2 distribution -0.05
Chi1 only 0.04
Chi3 & chi4 0.43
Omega 0.59
0.10
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.66
Main-chain bond angles 0.44
0.53
=====
OVERALL AVERAGE 0.28
=====
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.
