Mammalian cytochrome P450s provide our first line of defence against the toxic effects of environmental chemicals. Ironically these enzymes also convert some compounds to their ultimate toxic or mutagenic species. Our knowledge of these mammalian enzymes and the role they play in chemical toxicity and mutagenesis has stemmed mostly from in vitro studies. In(More)
This paper is to study and identify suitable algorithm that use in searching regulatory element where PhyloCon algorithm is one of the algorithms. Since PhyloCon has complexity limitation, the time performance is reduced. Therefore, a parallel technique is identified to improve performance of PhyloCon algorithm. The identified parallel technique is(More)
Mosquito coils are insecticides commonly used for protection against mosquitoes due to their toxic effects on mosquito populations. These effects on mosquitoes could induce the expression of metabolic enzymes in exposed populations as a counteractive measure. Cytochrome P450 family 4 (CYP4) are metabolic enzymes associated with a wide range of biological(More)
The increased frequency of antibiotic resistance is known to be associated with the dissemination of integrons in the Enterobacteriaceae. This study determined the prevalence and type of integrons amongst 160 extended-spectrum beta-lactamase producing enterobacterial isolates kept in our culture collection. Integrons were detected in 98(61.3%) (More)
Glutathione S-transferase (GST) from the 4th instar larvae of the dengue vector Aedes albopictus was purified by glutathione-agarose affinity chromatography and characterised using SDS-PAGE. The expression of the purified enzyme in the life stages and insecticide treated populations of Ae. albopictus as well as its cross-reactivity with larval GST of two(More)
Septins belong to GTPases that are involved in vital cellular activities, including cytokinesis. Although present in many organisms, they are yet to be isolated from Aedes albopictus. This study reports for the first time on a serendipitous isolation of a partial septin sequence from Ae. albopictus and its developmental expression profile. The Ae.(More)
OBJECTIVE To clone cytochrome P450 from Aedes aegypti (Ae. aegypti) and determine the characteristics using bioinformatics tools. METHODS Cytochrome P450 of Ae. aegypti was amplified using polymerase chain reaction, cloned and sequenced. Evolutionary relationship of the sequence was inferred and bioinformatics tools were used to predict subcellular(More)
Cytochrome P450 monooxygenase (P450) is a superfamily of enzymes that is important in metabolism of endogenous and exogenous compounds. In insects, these enzymes confer resistance to insecticides through its metabolic activities. Members of P450 from family 6 in insects are known to play a role in such function. In this study, we have isolated seven novel(More)
