End-residues (excl. Gly and Pro)            314

Glycine residues                            213
Proline residues                            142

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.
