Improving the Thermostability of Lipase by Restricting the Flexibility of N-Terminus and C-Terminus Simultaneously via the 25-Loop Substitutions.

(1) Lipases are catalysts widely applied in industrial fields. To sustain the harsh treatments in industries, optimizing lipase activities and thermal stability is necessary to reduce production loss. (2) The thermostability of lipase (TLL) was evaluated via B-factor analysis and consensus-sequence substitutions.

Discovery of the Key Mutation Site Influencing the Thermostability of Lipase by Rosetta Design Programs.

Lipases are remarkable biocatalysts and are broadly applied in many industry fields because of their versatile catalytic capabilities. Considering the harsh biotechnological treatment of industrial processes, the activities of lipase products are required to be maintained under extreme conditions. In our current study, Gibbs free energy calculations were performed to predict potent thermostable lipase (TLL) variants by Rosetta design programs.
