High impact information on alpha-Est5

  • Esterase-5 allozyme classes based on electrophoresis in 5% acrylamide gels are therefore highly heterogeneous [1].
  • Molecular evolution of the Sex-Ratio inversion complex in Drosophila pseudoobscura: analysis of the Esterase-5 gene region [2].
  • A 504-bp fragment of noncoding, intergenic DNA from the esterase-5 gene region was amplified and sequenced from 14 Sex-Ratio and 14 Standard X chromosomes of D. pseudoobscura, and from 9 X chromosomes of its two sibling species, Drosophila persimilis and Drosophila miranda [2].
  • A clone of the esterase-5 (Est-5) gene from Drosophila pseudoobscura has been isolated by hybridization to the cloned Est-6 gene of D. melanogaster [3].
  • The extremely close similarity in frequency distributions of the alleles between populations for both the xanthine dehydrogenase and esterase-5 loci, despite differences in allele frequency distribution between loci, strongly emphasizes the importance of migration in influencing genic diversity in these populations [4].
 

Biological context of alpha-Est5

 

Anatomical context of alpha-Est5

  • Disc gel electrophoresis of dissected adults of Drosophila pseudoobscura showed that most of the esterase-5 activity was in the head (36%) and thorax (51%), with little activity in the abdomen (13%) [8].
