Glucose 6-phosphate dehydrogenase in Drosophila: A sex-influenced electrophoretic variant

  • Donald J. Komma


A variant of glucose 6-phosphate dehydrogenase (G6PD) in Drosophila melanogaster shows different electrophoretic migration in males and females. In heterozygotes, the variant influences the migration of G6PD produced by both chromosomes. Mixing of homogenates of males and females changes migration of the female-produced enzyme, suggesting that a protein produced in males is capable of altering the variant G6PD molecule. The hypothetical protein is also present in pseudomales and intersexes produced by sex transformation genes.
