Enzyme-substrate interactions have occasionnaly been reported but you
usually have to mutate the ligand/bait in such a way as to prevent the
enzymatic reaction from being completed. For example, you can check the
paper by Wu et al. (JBC, 271:3265, 1996) => Interaction between the
kinases RAF and its substrate MEK are only observed when the serine
phosphorylation sites on MEK are mutated to alanines.
