초록

Glycoside hydrolase family 11 (GH11) xylanases are used in various industries, such as biorefining, animal feed production, and baking, making them key industrial enzymes. Operating bioprocesses at elevated temperatures enhances the reaction rate and product yield and thus requires thermostable enzymes to sustain catalytic performance. The limited availability of naturally occurring thermostable GH11 xylanases necessitates targeted modifications via protein engineering to enhance their thermal stability. In this review, we present the key drivers of thermostability, an overview of engineering strategies, and the underlying mechanisms of action. Finally, we investigated state-of-the-art technologies involving artificial intelligence (AI)- and ancestral sequence reconstruction-guided approaches.
