Abstract:
Molecular engineering of cellulases can improve enzymatic activity and efficiency. Recently, the Carbohydrate-Active enZYmes Database (CAZy), including glycoside hydrolase (GH) families, has been established with the development of Omics and structural measurement technologies. Molecular engineering based on GH families can obviously decrease the probing space of target sequences and structures, and increase the odds of experimental success. Besides, the study of cellulase active-site architecture paves the way toward the explanation of catalytic mechanism. This review focuses on the main GH families and the latest progresses in molecular engineering of catalytic domain. Based on the combination of analysis of a large amount of data in the same GH family and their conservative active-site architecture information, rational design will be an important direction for molecular engineering and promote the rapid development of the conversion of biomass.
