Activating Compound

Activating Compound Comment Organism Structure
DL-alpha-difluoromethylarginine plants exposed to 0.1 or 0.5 microM phenanthrene plus DL-alpha-difluoromethylarginine have significantly greater ADC activities when compared with plants treated with DL-alpha-difluoromethylarginine in the absence of phenanthrene Riccia fluitans
DL-alpha-difluoromethylornithine ADC activity increases by 21% in plants exposed to DL-alpha-difluoromethylornithine in the absence of phenanthrene Riccia fluitans
additional information DL-alpha-difluoromethylornithine does not influence the general trend of increased ADC activitiy observed in plants exposed to 0.1 or 0.5 microM phenanthrene Riccia fluitans
phenanthrene concentrations of phenanthrene up to 0.5 microM cause significant increases in the activity of ADC, with a resultant increase in tissue polyamine levels Riccia fluitans

Inhibitors

Inhibitors Comment Organism Structure
DL-alpha-difluoromethylarginine In the absence of phenanthrene, treatment with 1.5 mM DL-alpha-difluoromethylarginine with reduces ADC activity by 61% Riccia fluitans
additional information inhibition of ADC results in much greater levels of oxidative damage than seen in plants treated with 0.5 microM phenanthrene; treatment with DL-alpha-difluoromethylarginine suppresses the large increase in ADC activity observed when the plants are exposed to 0.1 or 0.5 microM phenanthrene in the absence of DL-alpha-difluoromethylarginine; treatment with methylglyoxal-bis(guanylhydrazone) does not significantly influence ADC activity Riccia fluitans
phenanthrene concentrations above 0.5 microM cause either no change or a significant reduction in ADC activity irrespective of treatment with or without DL-alpha-difluoromethylarginine Riccia fluitans
