Diffusion-controlled reaction on a sink with two active sites.
We have presented an exact solution for the problem of diffusive binding to a spherical macromolecule with two axially symmetric active patches. A highly accurate approximate formula for an effective steric factor has been suggested. This model solution may serve as a benchmark for further studies of diffusive interaction in more realistic models of anisotropic reactivity.
