PROCHECK summary for 2gyb
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 1551 79.1%**
Additional allowed regions [a,b,l,p] 353 18.0%
Generously allowed regions [~a,~b,~l,~p] 41 2.1%
Disallowed regions [XX] 17 0.9%*
---- ------
Non-glycine and non-proline residues 1962 100.0%
End-residues (excl. Gly and Pro) 40
Glycine residues 170
Proline residues 78
----
Total number of residues 2250
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 -0.70*
Chi1-chi2 distribution -0.14
Chi1 only 0.10
Chi3 & chi4 0.47
Omega 0.73
0.06
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.70
Main-chain bond angles 0.65
0.67
=====
OVERALL AVERAGE 0.29
=====
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.
