Role of the C-terminal extension stacked on the re-face of the isoalloxazine ring moiety of the flavin adenine dinucleotide prosthetic group in ferredoxin-NADP(+) oxidoreductase from Bacillus subtilis.

Abstract excerpt

Ferredoxin-NADP(+) oxidoreductase [EC 1.18.1.2] from Bacillus subtilis (BsFNR) is homologous to the bacterial NADPH-thioredoxin reductase, but possesses a unique C-terminal extension that covers the re-face of the isoalloxazine ring moiety of the flavin adenine dinucleotide (FAD) prosthetic group. In this report, we utilize BsFNR mutants depleted of their C-terminal residues to examine the importance of the...
