Thermostability Enhancement of the GH11 Xylanase XynZT-1 from Alteromonas macleodii HY35 Achieved via Modular Mosaic Engineering

and catalytic efficiency, respectively. The birchwood xylan hydrolysis assay confirmed the exceptional catalytic efficiency and thermostability of XynZ1, XynZ2, XynZ3, and XynZ4, highlighting their potential for industrial application, particularly in pulp prebleaching processes. These findings affirm that modular chimeric assembly is an effective engineering strategy for improving the performance of GH11 xylanases.
