Genetic and biochemical studies of the highly active esterases A' and B associated with organophosphate resistance in mosquitoes of the Culex pipiens complex.

abstract：:We describe a simple method for locating tryptophanyl-tRNA synthetase (E.C. 6.1.1.2) on cellulose acetate gels (Cellogel) following electrophoresis. Employing electrophoretic conditions which result in the separation of mouse and human tryptophanyl-tRNA synthetase, we have analyzed extracts of a number of independentl...

abstract：:Two types of alleles exist in the human alcohol dehydrogenase-2 (ADH2) locus. The usual ADH12 allele is common in Caucasians, while the atypical ADH22 allele is predominant in Orientals. The ADH22 produces the beta 2 subunit, which is catalytically far more active than the beta 1 subunit produced by the ADH12 gene. Th...
