Mechanism of the Aldolase Reaction.
Upon treatment with carboxypeptidase, muscle aldolase (ketose-l-phosphate aldehyde-lyase, EC 4.1.2.7) loses 3 COOHterminal tyrosine residues (3, 4) and exhibits a 20-fold fall in the rate of fructose diphosphate cleavage (3) and a 500-fold fall in the rate of exchange detritiation of dihydroxyacetone phosphate (5). The cleavage of fructose-l-P is relatively unchanged (3). The present investigat...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملGreat Britq , in A New Intermediate of the Aldolase Reaction , the Pyruvaldehyde - Aldolase - Orthophosphate Complex 361
Fructose 1,6-bisphosphate aldolase from rabbit muscle forms by reaction with dihydroxytacetone phosphate a pyruvaldehyde-aldolase-orthophosphate complex that is in equilibrium with the eneamine intermediate. The new intermediate accumulates in two phases. The first one is practically complete in 40ms, and the second occurs with an apparent first-order rate constant of 4.6+0.5s-1. The new interm...
متن کاملThe reaction of aldolase with 2-methylmaleic anhydride.
1. The reaction of rabbit muscle aldolase with 2-methylmaleic anhydride is described. All the protein amino groups can be reversibly blocked. 2. As the reaction proceeds, the enzyme activity decreases until, at about 50% citraconylation of amino groups, the enzyme is completely inhibited. At this stage, little or no dissociation of the enzyme tetramer is observed and 75% of the activity is reco...
متن کاملThe Mechanism of 2-keto-3-deoxy-6-phosphogluconic Aldolase.
In the original study of 2-keto-3-deoxy-6-phosphogluconic aldolase (I), and in subsequent experiments, the net synthesis of 2-keto-3-deoxy-6-phosphogluconate from the cleavage products could not be demonstrated. The present experiments were undertaken to clarify this point and to test the conformity of the reaction catalyzed by 2-keto-3-deoxy-6-phosphogluconic aldolase to the general characteri...
