Enzymatic methods of analysis
TLDR
An increase in the specificity of enzyme systems for the determination of pesticides is possible due to the effect of fifteen different pesticides including carbamates, chlorinated hydrocarbons and organophosphurus compounds on cholinesterase.Abstract:
The effect of fifteen different pesticides including carbamates, chlorinated hydrocarbons and organophosphurus compounds on cholinesterase from housefly, sugar boll weevll, fire ant and German cockroaches is reported. Since the cholinesterase from each source show different inhibition by various inhibitors, an increase in the specificity of enzyme systems for the determination of pesticides is possible.read more

The Effect of Carbon and Nitrogen Sources on the Level of Metabolic Intermediates in Escherichia coli
TL;DR: Measurements of the level of metabolic intermediates in acetate-grown cells, before and after the addition of glucose, suggest that isocitrate lyase is controlled in vivo by metabolites other than phosphoenolpyruvate, and that both isocite lyase and isOCitrate dehydrogenase play roles in regulating isocItrate utilization.
