ObjectiveThe 9_2 carbohydrate-binding module (C2) locates natively at the C-terminus of the GH10 thermophilic xylanase from Thermotoga marimita. When fused to the C-terminus, C2 improved thermostability of a GH11 xylanase (Xyn) from Aspergillus niger. However, a question is whether the C-terminal C2 would have a thermostabilizing effect when fused to the N-terminus of a catalytic module.ResultsA chimeric enzyme, C2-Xyn, was created by step-extension PCR, cloned in pET21a(+), and expressed in E. coli BL21(DE3). The C2-Xyn exhibited a 2 °C higher optimal temperature, a 2.8-fold longer thermostability, and a 4.5-fold higher catalytic efficiency on beechwood xylan than the Xyn. The C2-Xyn exhibited a similar affinity for binding to beechwood xylan and a higher affinity for oat-spelt xylan than Xyn.Conclusion
