In recent years, single-molecule experiments have emerged as a powerful
means to study biophysical/biochemical processes; many new insights are
obtained from this single-molecule perspective. One phenomenon recently
observed in single-molecule biophysics experiments is subdiffusion, which
largely departs from the classical Brownian diffusion theory. In this
talk, by introducing fractional Gaussian noise into the generalized
Langevin equation, we propose a model to describe the subdiffusion. We
will study the analytical properties of the model, compare the model
predictions with experiments, look at its connection with reaction
networks, and explore the implications of the model on enzyme reactions.
