Pea chloroplastic phosphoribulokinase and yeast phosphoriboisomerase partition independently of one another in a two‐phase polyethyleneglycol, dextran system, but apparent interaction is seen when ribose‐5‐phosphate is added to the two‐phase system. It appears that the pea leaf of kinase recognizes yeast isomerase when it is carrying metabolite.
