Residue-by-residue listing for refined_20 Page 1 ---------------------------------------- This listing highlights the residues in the structure which may need investigation. The ideal values and standard deviations against which the structure has been compared are shown in the following table: <------------------------------- I D E A L V A L U E S -------------------------------> Chi-1 dihedral Proline Phi Helix Chi-3 Chi-3 Disulph Omega H-bond Chirality g(-) trans g(+) Chi-2 phi helix psi rt-hand lf-hand bond dihedral en. C-alpha ------------------------------------------------------------------------------------------ Ideal value 64.1 183.6 -66.7 177.4 -65.4 -65.3 -39.4 96.8 -85.8 2.0 180.0 -2.0 33.9 Standard deviation 15.7 16.8 15.0 18.5 11.2 11.9 11.3 14.8 10.7 .1 5.8 .8 3.5 ------------------------------------------------------------------------------------------ In the listing below, properties that deviate from these values are highlighted by asterisks and plus-signs. Each asterisk represents one standard deviation, and each plus-sign represents half a standard deviation. So, a highlight such as +***, indicates that the value of the parameter is between 3.5 and 4.0 standard deviations from the ideal value shown above. Where the deviation is greater than 4.5 standard deviations its numerical value is shown; for example, *5.5*. The final column gives the maximum deviation in each row, while the maximum column deviations are shown at the end of the listing. Also at the end are the keys to the codes used for the secondary structure and Ramachandran plot assignments.
