Engineering Soluble Methane Monooxygenase (sMMO) through Optimized Screening Method for Improving Catalytic Efficiency toward Methane |
| 초록 |
Methane is a valuable resource in itself. But the resource has some issues hard to use. It exists as a gas making it expensive to transport to remote locations. Another issue is that methane is a potent greenhouse gas. It has global warming potential more than 20 times that of CO2. Methane monooxygenases (MMOs) are enzymes that catalyze of methane to methanol in methanotrophic bacteria. Through these enzymes, methane can be selectively converted to methanol in mild condition. But the conversion rate of the enzymes are pretty low. So they should be engineered to satisfy an industrially viable level. The inability to express MMOH (Hydroxylase) in a heterologous host limits their utilization in engineering. In our work, to manipulate sMMOH from Methylosinus trichosporium OB3b in E.coli strains, we chose a method called cell-free protein synthesis. And then we focused on optimizing enzymatic assay for screening to find clones that have higher catalytic acticity than that of Wild type MMOH. |
