Popis: The mechanism of bacimethrin (2) toxicity has been determined. This compound is converted to 2'-methoxy-thiamin pyrophosphate (10) by the thiamin biosynthetic enzymes. Of the seven thiamin pyrophosphate utilizing enzymes in Escherichia coli, 2'-methoxy-thiamin pyrophosphate inhibits alpha-ketoglutarate dehydrogenase, transketolase, and deoxy-D-xylulose-5-phosphate synthase. Bacimethrin does not cause repression of the genes coding for the thiamin biosynthetic enzymes.
