a Analysed for residues 1 to 50
b There are 46 residues with conformationally restricting constraints
c Calculated for all constraints for the given residues, using sum over r^-6
d Largest constraint violation among all the reported structures
e Residues with sum of phi and psi order parameters > 1.8
Ordered residue ranges: 4A-14A,17A-46A
f Residues selected based on: User defined residues
Selected residue ranges: 4A-14A,17A-46A
g With respect to mean and standard deviation for for a set of 252 X-ray structures < 500 residues, of resolution <= 1.80 Å, R-factor <= 0.25 and R-free <= 0.28; a positive value indicates a 'better' score
