Note: Summary report for depositors of a structure

This is an overall summary of the quality of the X-ray structure as compared with structures solved at similar resolutions. This summary can be useful for a crystallographer to see if the structure makes the best possible use of the data.

The second part of the table mostly gives an impression of how well the model conforms to common refinement constraint values. The first part of the table shows a number of constraint-independent quality indicators, which have been calibrated against structures of similar resolution.

Resolution found in PDB file : 1.90


Structure Z-scores, positive is better than average:

  1st generation packing quality :   1.3
