PROCHECK statistics
1. Ramachandran Plot statistics

No. of
residues %-tage
------ ------
Most favoured regions [A,B,L] 253 93.7%
Additional allowed regions [a,b,l,p] 17 6.3%
Generously allowed regions [~a,~b,~l,~p] 0 0.0%
Disallowed regions [XX] 0 0.0%
---- ------
Non-glycine and non-proline residues 270 100.0%

End-residues (excl. Gly and Pro) 2

Glycine residues 34
Proline residues 15
----
Total number of residues 321


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].

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.
