摘要
A family 22 carbohydrate-binding module (CBM22) from Clostridium stercorarium Xylanase10B raised the optimum temperature of the xylanase, but in the remaining activity of heating test, apparently the catalytic module alone showed higher remaining activity. Differential scanning calorimetry showed that CBM22 conferred resistance to thermal unfolding of the enzyme and prevented the enzyme from refolding after thermal unfolding.
