Abstract

The hydrolytic enzyme, trehalase, was isolated and purified approximately 90-fold from the cellular slime mold Dictyostelium discoideum. The purified trehalase has an optimal temperature of 45° C and shows maximum activity at pH 5.5 in citrate buffer. Its Michaelis constant is 1.2 × 10$^{-3}$M.
