New insights into the function and molecular mechanisms of Ferredoxin-NADP reductase from Brucella ovis.

Bacterial ferredoxin(flavodoxin)-NADP reductases (FPR) primarily catalyze the transfer of reducing equivalents from NADPH to ferredoxin (or flavodoxin) to provide low potential reducing equivalents for the oxidoreductive metabolism. In addition, they can be implicated in regulating reactive oxygen species levels. Here we assess the functionality of FPR from B.
