Cytogenetic localization of a putative regulatory gene affecting an NADP+-dependent enzyme in Drosophila melanogaster
Abstract
The cytogenetic localization of a putative regulatory locus affecting an NADP+-dependent enzyme is described. This locus, Mex, is in region 8D10-12 to 9A1-2 on the X chromosome of Drosophila melanogaster. Hyperploidy for this region is associated with significant increases in NADP+-dependent malic enzyme specific activity and specific immunologically cross-reacting material. This is the first report of a specific locus, unlinked to the locus coding for the major polypeptide of the enzyme, which affects an NADP+-dependent enzyme in Drosophila melanogaster.
