dszA (a monooxygenase gene )
DszA is a monoxygenase which can convert DBTsulfone (DBTO2) to 2-(2-hydroxybiphenyl) sulfinate (HBPS) during the 4S pathway, in which dibenzothiophene (DBT) undergoes three successive oxidation steps and one a hydrolytic step leading to the formation of 2-hydroxybiphenyl (2HBP). And DszA require reducing equivalents (FMNH2) supplied by a flavinreductase (DszD) while working.

The native dszABC operon was rearranged and the promoter was replaced in order to avoid overlapping genes, increase the expression of the dsz genes, especially dszB, which encoded the rate-limiting enzyme of the 4S-pathway, and relieve inhibition. Besides, a synthetic dszD cassette which was not linked to the dszABC genes in engineered bacteria IGTS8 was also constructed (Figure 1).
