Reaction catalyzed by aldolase
WebTransaldolase catalyzes a two- step conversion. The first step, an aldol cleavage of the bond between C-3 and C-4 of a ketose, is essentially identical to the reaction catalyzed by aldolase. However, the dihydroxyacetone that is produced in the transaldolase reaction from carbons 1, 2, and 3 is not released. Rather, it is held at the catalytic ... WebAldolase is likely ubiquitous to all cells, with larger concentrations present in muscle, liver, and brain tissues. Increases in aldolase levels have been detected in myotonic muscle …
