Abstract

In this project, we propose to investigate the dynamical behavior of several industrially important glycoside-hydrolases for second-generation bioethanol production through the use of molecular dynamics simulation. In this context, we aim to explore the following aspects: 1.Catalytic/processive dynamics towards solubilized and aggregated substrates;2.Enzyme-substrate affinity/interaction/binding;3.Local and global dynamics of enzyme adhesion and diffusion through long substrate chains and surfaces;4.Identification of non-productive enzyme-substrate bonded states;5.Enzyme stability under industrial conditions;6.Enzyme inhibition by reaction and industrial products;7.Mutation effects on all aspects cited above.
