Does biocatalysis involve inhomogeneous kinetics?

AbstractBiocatalytic reactions can occur according to two very different mechanisms: homogeneous, which is described by standard transition state theory (TST) and its modifications, and inhomogeneous (polychromatic), which is characteristic for some of the charge-transfer reactions in liquids and amorphous solids. While most data published on enzyme reactions are interpreted on the basis of homogeneous kinetics, the important recent findings suggest the involvement of inhomogeneous kinetics mechanism
