SOLVE Examples

This page gives three examples of what SOLVE can do. Each is an automatic structure determination carried out starting with raw data and a minimal amount of information from the user. In each case the top solution was correct and had the correct handedness (anomalous differences were used in each structure determination). The examples are:

For each structure determination, this page shows:
Gene 5 protein

Summary of this structure solution:

This is a dataset with 3-wavelengths of MAD data, 2800 reflections to 2.6 A, 87 amino acids, and 2 selenium sites (Met-1, Met-77). SOLVE found both selenium sites in 34 minutes on an DEC alpha 500 MHz workstation. The Met-1 site has a very high thermal factor.

Summary of this structure solution:

This is a dataset with 4 wavelengths of MAD data, 17000 reflections to 2.7 A, 537 amino acids, and 15 selenium sites. SOLVE found 14 selenium sites in 2 hours on a DEC Alpha 500 MHz workstation. The remaining 2 sites (one selenium has 2 positions) are very weak and were not included by SOLVE.

 Overall Z-score value:                                               58.8
Note that the Z-score for this solution (59) is much higher than for the gene 5 protein example, even though the phasing is about the same. This is because SOLVE scoring gets higher for datasets with more sites.

Granulocyte-macrophage colony stimulating factor

Summary of this structure solution:

This is an MIR dataset with 4800 reflections to 3.5 A, 4 derivatives, and 254 amino acids. The data is courtesy of Kay Diederichs. The derivatives are not that good and the overall figure of merit of the structure is only 0.54 to 3.5 A. Using all the data and including anomalous differences, SOLVE took 18 minutes to solve this MIR problem on a DEC Alpha 500 MHz workstation. Solve only used 3 of the 4 derivatives in phasing.
