PROCHECK summary for 2b9o
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 1565 75.7%**
Additional allowed regions [a,b,l,p] 391 18.9%
Generously allowed regions [~a,~b,~l,~p] 65 3.1%
Disallowed regions [XX] 46 2.2%*
---- ------
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 -0.91*
Chi1-chi2 distribution -0.84*
Chi1 only -0.23
Chi3 & chi4 0.45
Omega -0.49
-0.52*
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.48
Main-chain bond angles 0.34
0.40
=====
OVERALL AVERAGE -0.17
=====
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.
