PROCHECK summary for 4xk8
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 4730 89.8%*
Additional allowed regions [a,b,l,p] 515 9.8%
Generously allowed regions [~a,~b,~l,~p] 18 0.3%
Disallowed regions [XX] 6 0.1%*
---- ------
Non-glycine and non-proline residues 5269 100.0%
End-residues (excl. Gly and Pro) 55
Glycine residues 652
Proline residues 374
----
Total number of residues 6350
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 0.03
Chi1-chi2 distribution -0.12
Chi1 only 0.16
Chi3 & chi4 0.63
Omega 0.01
0.05
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.69
Main-chain bond angles 0.61
0.64
=====
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.
