The enzyme which catalyzes the conversion of D-erythrose 4-phosphate to D-erythrulose 4-phosphate and D-threose 4-phosphate has been purified to homogeneity from a crude extract of beef liver. Analysis of the purified enzyme by Sephadex G-100 gel filtration and sodium dodecyl sulfate/polyacrylamide gel electrophoresis revealed it to be a dimer of relative molecular mass 43 000. From the gas chromatography/mas spectrometry analyses of the enzymatic reaction products, it appeared that about 90% of the total amount of tetrose 4-phosphate was present as D-erythrulose 4-phosphate after equilibration. The purified enzyme, which is tentatively called 'erythrose-4-phosphate isomerase' had no significant isomerase activities on D-glyceraldehyde 3-phosphate, D-ribose 5-phosphate, D-glucose 6-phosphate and D-fructose 6-phosphate, but a strong D-ribulose-5-phosphate 3-epimerase activity was co-purified with the erythrose-4-phosphate isomerase activity through every step in the isolation. Both the erythrose-4-phosphate isomerase and D-ribulose-5-phosphate 3-epimerase activities were inactivated at the same rate at the elevated temperature, and also inhibited to the same extent by various inhibitors. It is likely, that both activities are catalyzed by the single enzyme protein. << Less
