Discovering and Designing a Chimeric Hyperthermophilic Chitinase for Crystalline Chitin Degradation

Sun, Bo; Zhao, Xingchu; Xu, Birui; Su, Erzheng; Kovalevsky, Andrey;

2023 ACS Sustainable Chemistry & Engineering

doi:10.1021/acssuschemeng.2c07050

Chitin is one of the most abundant renewable biopolymers on earth. However, it is highly crystalline and recalcitrant to degrade. Here, we report a hyperthermophilic chitinase (ActChi) to directly hydrolyze crystalline chitin at its optimal temperature of 80 °C. It contains a malectin domain, a...
