Anomalous scattering sites located by Phaser-EP from two merged Q619M data sets in successive cycles of map completion (cycles indicated by gaps between sets), showing Z-scores (vertical axis) for each site. Blue bars indicate `core' methionines, the gold bar indicates the hinge site ascribed to the methionine point mutant (Q619M), grey bars indicate `core' methionine alternative conformations and the green bar was interpreted as a chloride ion. |
