Abstract excerpt
To improve the thermostability of the lipase (r27RCL) from Rhizopus chinensis through rational design, a newly introduced buried disulfide bond F223C/G247C was proved to be beneficial to thermostability. Interestingly, F223C/G247C was also found to improve the alkali tolerance of the lipase. Subsequently, six other thermostabilizing mutations from our previous work were integrated into the mutant F223C/G247C,...
