PROCHECK summary for 2b9p
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 872 33.4%**
Additional allowed regions [a,b,l,p] 1036 39.7%
Generously allowed regions [~a,~b,~l,~p] 453 17.4%
Disallowed regions [XX] 246 9.4%**
---- ------
Non-glycine and non-proline residues 2607 100.0%
End-residues (excl. Gly and Pro) 75
Glycine residues 257
Proline residues 138
----
Total number of residues 3077
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 -2.18**
Chi1-chi2 distribution -1.09**
Chi1 only -0.18
Chi3 & chi4 0.51
Omega -0.37
-0.91*
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.42
Main-chain bond angles 0.26
0.33
=====
OVERALL AVERAGE -0.43
=====
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.
