Studies on the characteristics of xylanase

The characteristics of the xylanase from Trichoderma reesei strain GXC were studied. The results showed that the optimal temperature was 55℃ and pH 5.3 respectively, the range of pH stability was wide, the enzyme was stable below 40 ℃. Cu<sup>2+</sup>, Zn<sup>2+</sup>, Fe<...

description The characteristics of the xylanase from Trichoderma reesei strain GXC were studied. The results showed that the optimal temperature was 55℃ and pH 5.3 respectively, the range of pH stability was wide, the enzyme was stable below 40 ℃. Cu<sup>2+</sup>, Zn<sup>2+</sup>, Fe<sup>2+</sup> and Fe<sup>3+</sup> had inhibitory effect on the enzyme activity, but Co<sup>2+</sup> and Mn<sup>2+</sup> could stimulate the activity. Vmax was 526 μmol / (min·mg), Km was 3.42 mg/mL.
