【Abstract】

<正>Enzyme thermostability is of importance for widening the application spectra of enzymes.In our studies,a structure-based rational design approach was used to improve the enzyme thermostability via the optimization of charge-charge interactions.A highly active endo-P-l,3-l,4-glucanase(77glul6A)from Talaromyces leycettanus JCM 12802 and an endopolygalacturonase(PG8fn)from Achaetomium sp.Xz8
