Replacing a piece of loop-structure in the substrate-binding groove of Aspergillus usamii β-mannanase, AuMan5A, to improve its enzymatic properties by rational design
To perfect the enzymatic properties of AuMan5A, a mesophilic glycoside hydrolase (GH) family 5 β-mannanase from Aspergillus usamii, its loop-structure substitution was carried out by rational design and followed ...

Improvement in the thermostability of a type A feruloyl esterase, AuFaeA, from Aspergillus usamii by iterative saturation mutagenesis
Feruloyl or ferulic acid esterase (Fae, EC 3.1.1.73) catalyzes the hydrolysis of ester bonds between polysaccharides and phenolic acid compounds in xylan side chain. In this study, the thermostability of a typ...
