Figure 2
X-ray crystal structure of PatF. (a) `Chainbows' representation of the asymmetric unit showing the presence of two molecules. (b) Secondary-structure representation of the PatF monomer; [alpha]-helices are shown in red and [beta]-sheets are shown in yellow. PatF is formed by a 12-stranded antiparallel [beta]-barrel surrounded on the outside by 12 [alpha]-helices, with [alpha]-helix 1 protruding out from the rest of the structure.  [article HTML]
