PROCHECK summary for 2qnh
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 1161 56.0%**
Additional allowed regions [a,b,l,p] 689 33.3%
Generously allowed regions [~a,~b,~l,~p] 150 7.2%
Disallowed regions [XX] 72 3.5%*
---- ------
Non-glycine and non-proline residues 2072 100.0%
End-residues (excl. Gly and Pro) 30
Glycine residues 190
Proline residues 109
----
Total number of residues 2401
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 -1.61**
Chi1-chi2 distribution -1.02**
Chi1 only -0.32
Chi3 & chi4 0.45
Omega 0.02
-0.61*
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.51
Main-chain bond angles 0.39
0.44
=====
OVERALL AVERAGE -0.21
=====
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.
