Reaction catalyzed by aldolase
Web"The enzyme aldolase catalyzes the following reaction in the glycolytic pathway: Aldolas Fructose 1, 6 bisphosphate dihydroxyacetone phosphate + glyceraldehyde 3 phosphate … WebThe pathway consists of a series of enzymatic reactions, each catalyzed by a specific enzyme. When [14C1,6]-Fructose-1,6[32P]-Bisphosphate enters the glycolytic pathway, it is cleaved by the enzyme aldolase into two molecules of glyceraldehyde-3-phosphate (GAP).
