Abstract
MamA is a unique magnetosome-associated protein that is predicted to contain six sequential tetratricopeptide-repeat (TPR) motifs. The TPR structural motif serves as a template for protein-protein interactions and mediates the assembly of multi-protein complexes. Here, the crystallization and preliminary X-ray analysis of recombinant and purified Magnetospirillum magneticum and M. gryphiswaldense MamA are reported for the first time. M. gryphiswaldense MamADelta41 crystallized in the tetragonal space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters a = b = 58.88, c = 144.09 A. M. magneticum MamADelta41 crystallized in the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 44.75, b = 76.19, c = 105.05 A. X-ray diffraction data were collected to resolutions of 2.0 and 1.95 A, respectively.
