WebMay 29, 2009 · When 2 μM dioctylamine was added to the reaction, the rate was reduced by 50%, indicating a fairly potent inhibition against the enzyme and consistency with dioctylamine inhibition of the cyclopropane fatty acid synthase from E. coli. These data demonstrate that dioctylamine is a direct inhibitor of mycolic acid methyltransferases. WebGenetic predictions indicate that the cyclopropane fatty acid (CFA) pathway is present, conferring acid-resistance properties to the cells. The two novel strains might possess a class IV polyhydroxyalcanoate (PHA) synthase operon involved in the P3HB production pathway. Overall, the polyphasic taxonomic analysis shows that these two novel ...
