Crystallization and preliminary X-ray analysis of the outer membrane pyoverdine receptor FpvA from Pseudomonas aeruginosa.
FpvA, the pyoverdine outer-membrane receptor from Pseudomonas aeruginosa, is involved in iron uptake when bacteria grow under iron limitation. Crystals of the in vivo pyoverdine-loaded FpvA were obtained under several crystallization conditions using different detergents. A native data set was collected at 3.6 A resolution and a three-wavelength MAD data set was collected at 3.6 A resolution using crystals of selenomethionine-substituted protein. The crystals grew under similar conditions and both belong to space group C2, but have different unit-cell parameters.
