Copyright policy )Sulfite Reductase of Escherichia coli Is a Ferrisiderophore Reductase
A soluble ferrisiderophore reductase activity of Escherichia coli was purified to homogeneity and identified as the sulfite reductase. The pure enzyme catalyzes the reduction of ferric citrate, ferriaerobactin, ferrioxamin, ferricrocin, ferrichrome and ferrifusarinin by NADPH. Free flavins, riboflavin, FMN, FAD were absolutely required, suggesting that this activity resides in the flavin reductase activity of sulfite reductase.
