PROCHECK summary for 2kax
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 143 83.1%*
Additional allowed regions [a,b,l,p] 20 11.6%
Generously allowed regions [~a,~b,~l,~p] 4 2.3%
Disallowed regions [XX] 5 2.9%*
---- ------
Non-glycine and non-proline residues 172 100.0%
End-residues (excl. Gly and Pro) 4
Glycine residues 6
Proline residues 2
----
Total number of residues 184
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 -0.51*
Chi1-chi2 distribution -0.82*
Chi1 only 0.08
Chi3 & chi4 0.07
Omega -1.01**
-0.60*
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.45
Main-chain bond angles -0.42
-0.06
=====
OVERALL AVERAGE -0.38
=====
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.
