Duplication, dicistronic transcription, and subsequent evolution of the Alcohol dehydrogenase and Alcohol dehydrogenase-related genes in Drosophila.
It has recently been discovered that the Alcohol dehydrogenase and Alcohol dehydrogenase-related genes of Drosophila melanogaster and closely related species constitute a single transcription unit and that the Alcohol dehydrogenase-related gene is exclusively expressed from a dicistronic mRNA. Here, we show that in Drosophila lebanonensis, subgenus Scaptodrosophila, Adhr: is also transcribed as...
متن کاملThe molecular evolution of the alcohol dehydrogenase and alcohol dehydrogenase-related genes in the Drosophila melanogaster species subgroup.
The DNA sequences of the Adh genes of three members of the Drosophila melanogaster species subgroup have been determined. This completes the Adh sequences of the eight species of this subgroup. Two species, D. yakuba and D. teissieri, possess processed Adh pseudogenes. In all of the species of the subgroup, a gene of unknown function, Adhr, is located about 300 bp 3' to Adh. Although this gene ...
متن کاملOrganization and evolution of the alcohol dehydrogenase gene in Drosophila.
The alcohol dehydrogenase (Adh) gene was isolated from Drosophila simulans and D. mauritiana, and the DNA sequence of a 4.6-kb region, containing the structural gene and flanking sequence, was determined for each. These sequences were compared with the Adh region of D. melanogaster to characterize changes that occur in the Drosophila genome during evolution and to identify conserved sequences o...
متن کاملDrosophila Alcohol Dehydrogenase
Drosophila alcohol dehydrogenasc (alcohol:NADf oxidorcduct.ase, EC 1.1.1.1) has attracted attention in several laboratories (l-3) recently. Genetic variants of this enzyme were found, and consequently it was possible to determine its structural locus on the genetic map. The specific activity of alcohol dehydrogenase varies greatly along the t.ime axis of devcloprnent of this organism, and it oc...
