Abstract

Specific activity of soluble trehalase from Drosophila melanogaster has been increased at least 10 times by preparative electrophoresis using selective unstacking. However, enzyme yield was poor, with only 17% of the original activity recovered. A comparison of Km of crude and partially purified trehalase revealed no difference (0.650 and 0.666 mm, respectively). Electrophoretic parameters for a modified version of multiphasic buffer system 4014 are described and electrophoretic parameters which may be utilized in the electrophoretic purification of trehalase from 17 species of Drosophila are reported.
