We have just solved a structure working with SOLES colleague Tara Christie (not to mention Toby Passioura and Rich Payne). The structure determination was a bit of a wrestle for Tara (as you’d expect at 3.9 A!), but gee – you can’t help but love the packing in the crystal (side-on and end-on views provided). Maybe we should be using this protein to make nanotubes!
