Fig. 4From: Mutagenesis of N-terminal residues confer thermostability on a Penicillium janthinellum MA21601 xylanaseDSC results of PjxA (blue line), PTxA (purple line), PjxA-DB (red line) and PTxA-DB (green line). All samples were adjusted to 0.5 mg/mL and dialyzed against 50 mM sodium acetate buffer (pH 5.5) before measuring by DSC. A graph was generated by the Launch Nano Analyze softwareBack to article page
