Characterize the Thermodynamic Forces of Decomposing a Cellulose Microfibril
EMSL Project ID
39990
Abstract
To develop viable technologies for the enzymatic decomposition and conversion of cellulosic materials into fuels, mechanistic understanding of the molecular processes that are involved is in urgent need. The allocation from this request will be employed to characterize the thermodynamic forces of three essential processes of enzymatic cellulose decomposition: (a) peeling a glucose chain from the surface of a microfibril, (b) detaching a glucose chain from the active site of the endoglucanase I (EG1) from Trichoderma reesei, and (c) the binding of the cellulose binding domain of EG1 onto the surfaces of a cellulose microfibril. Novel reaction path optimization schemes developed by us will be used to inform suitable order parameters for free energy simulations. A proven scalable engine, NAMD, will be used for all-atom molecular dynamics simulations in explicit solvent.
