In order to improve the enzyme properties of the Penicillum expaasum lipase(PEL), the PEL gene was mutated by site-mutagenesis and random mutagenesis. 1. Site-directed mutagenesis of PEL
In order to improve the thermostability of Penicillium expansum lipase (PEL), Eleven mutations were created by site-directed mutagenesis. Mutations were generated by overlap extension PCR using the cDNA of wild-type lipase gene(lip07) or a single site mutant lipase ep8 as the template and two special primers that corres...
