Structural asymmetry of AcrB trimer suggests a peristaltic pump mechanism

The structure of AcrB in spacegroup C2 was solved by molecular replacement (using the symmetric structure as a model), followed by many cycles of refinement and model building. The raw data are available at ftp://turn5.biologie.uni-konstanz.de/pub/datasets/ .

The goal of this XDSwiki project is to run different versions of XDS (and other data reduction programs if anybody would contribute the data reductions!), and to compare internal R-factor statistics against R-factors of the refined model.

More to come!
