Some evidence in favour of the partnership between rabbit muscle aldolase and glyceraldehyde 3-phosphate dehydrogenase in the consecutive reactions.

An additional indication in favour of interaction between sequential glycolytic enzymes is provided by the mutual enhancement of aldolase and glyceraldehyde 3-phosphate dehydrogenase activities. The efficiency of aldolase as the activator is progressively affected by the presence of its substrate, fructose-1,6-diphosphate, and its structural analogue, hexitol-1,6-diphosphate. Such interrelation of two sequential glycolytic enzymes can originate from their conformational interadjustment for the subsequent metabolic channeling between them.
