experimental model | Other | The structure was solved with data from a Ta6Br14 soaked crystal at low resolution (5.2A) by SAD with SHELX and HKL2MAP using the anomalous Ta signal. Identifiable alpha-helices were manually placed and used as a starting model for SAD-MR by exploiting the anomalous Se signal from Se-Met derivatised crystal,using the program Phenix Autosol. The structure was finally modelled and refined using the natived data submitted. |
