Mutagenesis of N-terminal residues confer thermostability on a Penicillium janthinellum MA21601 xylanase

Abstract Background A mesophilic xylanase PjxA from Penicillium janthinellum MA21601 has high specific activity under acidic condition and holds great potential for applications in the animal feed industry. To enhance the thermostability of xylanase PjxA, two mutation strategies in the N-terminal re...
