D-Glyceraldehyde 3-phosphate = glycerone phosphate
in situ magnetic resonance probes of the enzyme-bound substrates to test the question of whether the equilibrium concentrations are perturbed by the enzyme. In the exergonic conversion of glycerinaldehyde 3-phosphate to dihydroxyacetone phosphate the high discrimination against solvent isotope uptake is consistent with chemistry protected by a water-tight active-site loop, therefore introducing asymmetry into the reversible reaction
-
D-Glyceraldehyde 3-phosphate = glycerone phosphate
intrinsic binding energy of the substrate phosphodianion group is utilized to drive closing of the mobile loop and a protein conformational change that leads to formation of an active site environment that is optimally organized for stabilization of the transition state for proton transfer from R-carbonyl carbon
-
D-Glyceraldehyde 3-phosphate = glycerone phosphate
upon binding of ligand, the side chain of Glu167 flips from the inactive swung-out to the active swung-in conformation. A concerted movement of loop 6 and loop 7 from unliganded-open to liganded-closed is facilitated by the interactions of the phosphate moiety with loop 7. Rotation of the Gly211-Gly212 peptide plane of 90° is involved in this concerted movement
D-Glyceraldehyde 3-phosphate = glycerone phosphate
the active site of free enzyme, which has an open conformation needed to allow substrate binding, adopts a closed conformation at the enediolate-complex intermediate where the catalytic side chain is sequestered from interaction with imidazole dissolved in D2O

formation of a two-part substrate by carving up D-glyceraldehyde 3-phosphate into the minimal neutral two-carbon sugar glycolaldehyde and phosphite dianion pieces. Enzyme catalyzes proton transfer from glycolaldehyde in D2O with a ratio of kcat to Km of 0.26 per M and s. Addition of exogenous phosphite dianion results in a large increase in the observed second-order rate constant for turnover of glycolaldehyde. Binding of phosphite dianion to the free enzyme is 700fold weaker than its binding to the fleeting complex of the enzyme with the altered substrate in the transition state
