PROCHECK summary for 1sif
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 59 95.2%
Additional allowed regions [a,b,l,p] 2 3.2%
Generously allowed regions [~a,~b,~l,~p] 1 1.6%
Disallowed regions [XX] 0 0.0%
---- ------
Non-glycine and non-proline residues 62 100.0%
End-residues (excl. Gly and Pro) 2
Glycine residues 4
Proline residues 3
----
Total number of residues 71
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 -0.16
Chi1-chi2 distribution 0.01
Chi1 only -0.11
Chi3 & chi4 0.55
Omega -0.87*
-0.27
=====
Main-chain covalent forces:-
Main-chain bond lengths 0.12
Main-chain bond angles 0.00
0.05
=====
OVERALL AVERAGE -0.14
=====
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.
