ANABAENA PCC7119 FERREDOXIN:FERREDOXIN-NADP+-REDUCTASE COMPLEX
Overview
Ferredoxin-NADP(+) reductase (FNR) and its physiological electron donor, ferredoxin (Fd) from the cyanobacterium Anabaena PCC7119 have been, co-crystallized. The unit-cell parameters are a = b = 63.72, c = 158.02 A, and the space group is P2(1)2(1)2(1). The crystal structure has been, solved with 2.4 A resolution synchrotron data by molecular replacement, anomalous dispersion and R(min) search methods. For the computations, the, crystal was treated as a merohedral twin. The asymmetric unit contains two, FNR molecules and one ferredoxin molecule. The packing of the FNR, molecules displays a nearly tetragonal symmetry (space group P4(3)2(1)2), whereas the ferredoxin arrangement is orthorhombic. This study provides, the first crystallographic model of a dissociable complex between FNR and, Fd.
