title: Purification, characterization and crystallization of enzymes for dibenzothiophene desulfurization.
abstract: DszC and DszA, DBT monooxygenase and DBT sulfone monooxygenase, respectively, involved in dibenzothiophene (DBT) desulfurization, were purified to homogeneity from Rhodococcus erythropolis D-1. The two enzymes were crystallized and enzymologically characterized. We found a high activity of flavin reductase in the non-DBT-desulfurizing bacterium, Paenibacillus polymyxa A-1, which is essential for DszC and A activities, and purified to homogeneity and characterized the enzyme.
