Post-translational control of alcohol dehydrogenase levels in Drosophila melanogaster.

ABSTRACT

A trans-acting regulatory gene that alters in vivo protein levels of alcohol dehydrogenase (ADH) has been mapped to a region of the third chromosome of Drosophila melanogaster. The gene has been found to affect the in vivo stability of ADH protein. It was not found to alter levels of total protein of two other enzymes assayed. The action of the gene over development and its possible mode of control are discussed.
