Abstract: Carbohydrate-active enzymes (CAZymes), such as glycoside hydrolases and glycosyltransferases, constitute the main machinery for the degradation, synthesis and modification of carbohydrates in nature. They have a myriad of industrial and biotechnological applications, ranging from biofuel production to biotherapeutics. In recent years, new CAZyme structures have been solved that pose mechanistic questions on how their carbohydrate substrates are processed, such as the identity of the catalytic residues, the role of enzyme conformational transitions and the distortion of the substrate at the transition state of the chemical reaction. Using state-of-art simulation techniques such as ab initio quantum mechanics/molecular mechanics (QM/MM) and metadynamics we have contributed to answer these questions, providing an atomistic view of enzyme action that can guide inhibitor design. In this talk I will describe some of the CAZyme mechanisms that we have recently investigated, in a collaborative work with research groups of structural and chemical biology.
