Abstract

A fourth recently discovered isozyme of sn-glycerol-3-phosphate dehydrogenase (GPDH-4) in Drosophila melanogaster is shown to be a translational product of the Gpdh transcript which contains exons 1 through 7. This transcript was also found in two other Drosophila species, D. busckii and D. virilis. In contrast to D. melanogaster and D. busckii, the Gpdh transcript containing exons 1-6 is absent in D. virilis adults. The reason for this difference between D. virilis and the two other species is intriguing but remains elusive. We have ruled out the possibility that a replacement of an amino acid residue in exon 7 played any role in generating this interspecific variation.
