FERREDOXIN:NADP+ REDUCTASE MUTANT WITH LYS 75 REPLACED BY GLN (K75Q)

Overview

The three-dimensional structures of K72E, K75R, K75S, K75Q, and K75E, Anabaena Ferredoxin-NADP+ reductase (FNR) mutants have been solved, and, particular structural details of these mutants have been used to assess, the role played by residues 72 and 75 in optimal complex formation and, electron transfer (ET) between FNR and its protein redox partners, Ferredoxin (Fd) and Flavodoxin (Fld). Additionally, because there is no, structural information available on the interaction between FNR and Fld, a, model for the FNR:Fld complex has also been produced based on the, previously reported crystal structures and on that of the rat Cytochrome, P450 reductase (CPR), onto which FNR and Fld have been structurally, aligned, and those reported for the Anabaena and maize FNR:Fd complexes., The model ...
