studies by dynamic and total intensity light scattering , ultracentrifugation , electron microscopy , and chemical crosslinking on solutions of the pig heart mitochondrial enzymes , malate dehydrogenase and citrate synthase ( separately and together ) demonstrate that polyethylene glycol induces very large homoassociations of each enzyme , and still larger heteroenzyme complexes between these two enzymes in the solution phase .
