General Information

General Information Comment Organism
physiological function SoeABC is the major sulfite-oxidizing enzyme in Allochromatium vinosum. The periplasmic sulfur substrate-binding protein SoxYZ is needed in parallel to the cytoplasmic enzymes for effective sulfite oxidation. A SoeABC-deficient mutant displays about 17% of wild-type sulifte oxidation. A knockout of both adenosine-5'-phosphosulfate reductase gene aprB and soeA leads to an additive effect with a residual specific rate of sulfite oxidation for whole cells of only 7% Allochromatium vinosum
