Activating Compound

Activating Compound Comment Organism Structure
additional information NADPH-preferring flavin reductase from Paenibacillus polymyxa A-1 increases the catalytic activity of enzyme DszA 5fold compared to the activity with Rhodococcus erythropolis strain D-1 flavin reductase. The flavin reuctase from Vibrio harveyi is also stimulating. In the microbial DBT-desulfurization, flavin reductase from the non-DBT-desulfurizing bacterium is superior to that from the DBT-desulfurizing bacterium Rhodococcus erythropolis

General Information

General Information Comment Organism
metabolism the enzyme is involved in the dibenzothiophene desulfurizing metabolizing dibenzothiophene to form 2-hydroxybiphenyl without breaking the carbon skeleton, dibenzothiophene desulfurization pathway, overview Rhodococcus erythropolis
physiological function DszC and DszA catalyze monooxygenation reactions in the desulfurization of dibenzothiophene, both requiring the additional enzyme flavin reductase, which catalyzes the reduction of flavin by NAD(P)H to form reduced flavin Rhodococcus erythropolis
