Chemical basis of the electrophoretic variation observed at the alcohol dehydrogenase locus of Drosophila melanogaster.

The amino acid substitution responsible for the different electrophoretic mobility of the ADHs alleloenzyme and the ADHf alleloenzyme of the alcohol dehydrogenase from a Nigerian population of Drosophila melanogaster has been established as lysine (ADHs) for threonine (ADHf). This result is discussed with reference to the charge state model of… CONTINUE READING
