PROCHECK summary for 4tt3
Ramachandran plot
PROCHECK statistics
1. Ramachandran Plot statistics
No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 2429 90.3%
Additional allowed regions [a,b,l,p] 256 9.5%
Generously allowed regions [~a,~b,~l,~p] 5 0.2%
Disallowed regions [XX] 1 0.0%*
---- ------
Non-glycine and non-proline residues 2691 100.0%
End-residues (excl. Gly and Pro) 33
Glycine residues 287
Proline residues 123
----
Total number of residues 3134
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

Dihedral angles:-
Phi-psi distribution -0.16
Chi1-chi2 distribution 0.21
Chi1 only 0.06
Chi3 & chi4 0.56
Omega -0.04

Main-chain covalent forces:-
Main-chain bond lengths 0.66
Main-chain bond angles 0.62
0.63
=====
OVERALL AVERAGE 0.28

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.
