Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 3485 78.1%**
Additional allowed regions [a,b,l,p] 867 19.4%
Generously allowed regions [~a,~b,~l,~p] 85 1.9%
Disallowed regions [XX] 27 0.6%*
---- ------
Non-glycine and non-proline residues 4464 100.0%
End-residues (excl. Gly and Pro) 72
Glycine residues 480
Proline residues 270
----
Total number of residues 5286
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 -0.71*
Chi1-chi2 distribution -0.36
Chi1 only -0.03
Chi3 & chi4 0.48
Omega 0.55
-0.09
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.51
Main-chain bond angles 0.32
0.40
=====
OVERALL AVERAGE 0.12
=====
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.
