additional information | the enzyme from Pseudomonas aeruginosa does not depend on glutathione for catalysis. The enzyme requires only NAD+ as the electron carrier, and addition of glutathione has no effect on the catalytic activity, indicating glutathione-independent catalysis | Pseudomonas aeruginosa |
Cloned (Comment) | Organism |
---|---|
recombinant expression of His-tagged enzyme in Escherichia coli strain BL21(DE3)/pG-TF2. 50% of the recombinant proteins are localized in the supernatant fraction of cell-free extract, suggesting that coexpression with chaperones GroES, GroEL, and Tig has significantly improved the solubilization of Pseudomonas aeruginosa FDH in Escherichia coli | Pseudomonas aeruginosa |
Crystallization (Comment) | Organism |
---|---|
purified recombinant His-tagged enzyme, sitting drop vapor diffusion method, mixing of 0.001 ml of 15 mg/ml protein in 10 mM Tris-HCl. pH 8.0, and 1 mM DTT with 0.001 ml of reservoir solution containing 0.1 M Bis-Tris, pH 5.5, and 1.8 M ammonium sulfate, at 18°C, X-ray diffraction structure determination and analysis at 2.7 A resolution, molecular replacement method, and modelling | Pseudomonas aeruginosa |

General Information | Comment | Organism |
---|---|---|
evolution | the enzyme is a member of zinc-containing medium-chain alcohol dehydrogenase family | Pseudomonas aeruginosa |
physiological function | the enzyme oxidizes toxic formaldehyde to less active formate using NAD+ as a cofactor. The enzyme requires only NAD+ as the electron carrier, and addition of glutathione has no effect on the catalytic activity, indicating glutathione-independent catalysis | Pseudomonas aeruginosa |
