Looking at structure. Professor Rod. E. Hubbard (York)
Chair: Andrew Leslie (Cambridge).
This session will cover all experimental aspects of structure determination by the MAD method from selenomethionine expression to locating the sites as well as novel developments in the field such as the exploitation of the anomalous signal from biologically occurring elements.
