Crystallization (Comment) | Organism |
---|---|
purified recombinant His-tagged enzyme in apoform and as FMN-bound enzyme DszC, two distinct conformations occur in the loop region (residues 131-142) adjacent to the active site, sitting drop vapor diffusion method, mixing of 0.001 ml protein solution with 0.001 ml of reservoir solution consisting of 0.2 M malonate, pH 6.0, 24% w/v PEG 3350, and 50 mM NaF, at 20°C, with or without 1 mM FMN, X-ray diffraction structure determination and analysis at 2.11 A an 2.3 A resolution, respectively, Each crystal contains two tetramers in the asymmetric unit, formed by two homodimers | Rhodococcus erythropolis |

General Information | Comment | Organism |
---|---|---|
metabolism | the DBT monooxygenase from Rhodococcus erythropolis D-1 is involved in the first two steps of the 4S pathway. The 4S metabolic pathway catalyzes the sequential conversion of DBT to 2'-hydroxybiphenyl via three enzymes encoded by the dsz operon in several bacterial species | Rhodococcus erythropolis |
additional information | C-terminal DBT-binding site by using a molecular docking simulation that simultaneously docks the FMN cofactor and DBT substrate to an apo-DszC structure, role of the C terminus in catalysis | Rhodococcus erythropolis |
