PROCHECK summary for 1xnq
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 1498 72.5%**
Additional allowed regions [a,b,l,p] 467 22.6%
Generously allowed regions [~a,~b,~l,~p] 72 3.5%
Disallowed regions [XX] 30 1.5%*
---- ------
Non-glycine and non-proline residues 2067 100.0%
End-residues (excl. Gly and Pro) 30
Glycine residues 191
Proline residues 108
----
Total number of residues 2396
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 -1.00*
Chi1-chi2 distribution -0.43
Chi1 only -0.08
Chi3 & chi4 0.45
Omega 0.61
-0.12
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.64
Main-chain bond angles 0.40
0.50
=====
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.
