MAD phasing was not used to solve 1EL9 and 1ELI, but rather direct refinement as the crystals were isomorphous enough to the native crystals for phasing. Selenomethionine crystals were used for the experiments since they were the only ones on hand at the time. Kinetic studies showed that the presence of selenomethionine had little effect.
