Metagenomics is a modern approach to discovery of new enzymes with novel properties. This article reports the structure of a new lipase, belonging to family I.1, obtained by means of metagenomics. Its structure presents a fold typical of α/β hydrolases, with the lid in closed conformation. The protein was previously shown to present high thermostability and to be stable in aqueous solutions of polar organic solvents at high concentrations [30% (V/V)]. Molecular dynamics studies showed that the protein maintains its structure well in organic solvents. They also suggested that its thermostability might be enhanced if it were mutated to present a disulfide bond similar to that typically found in lipase family I.2. These findings identify this lipase as a good candidate for further improvement through protein engineering.
