Abstract
|
|
|
Dibenzothiophene (DBT) and its derivatives are typical sulfur compounds found in
fossil fuels. These compounds show resistance to the hydrodesulfurization
treatment that is commonly used in industry. Dibenzothiophene monooxygenase
(DszC) is responsible for the oxidation of DBT, which is the first and the
rate-limiting step in the DBT enzymatic desulfurization 4S pathway. In this
study, the crystal structure of DszC from Rhodococcus erythropolis DS-3 is
reported. The crystal of native DszC belonged to space group P1, with unit-cell
parameters a = 96.16, b = 96.27, c = 98.56 Å, α = 81.03, β = 67.57, γ =
85.84°. To determine the phase, SAD X-ray diffraction data were collected from
a SeMet-derivative DszC crystal, which also belonged to space group P1, with
unit-cell parameters a = 95.379, b = 95.167, c = 94.891 Å, α = 87.046, β =
70.536, γ = 79.738°. Further structural analysis of DszC is in progress.
