1 | DL-alpha-Difluoromethylornithine (DFMO) and DL-alpha-difluoromethylarginine (DFMA), specific, irreversible ("suicide") inhibitors of ODC and ADC in vitro, were used to modulate PA biosynthesis in excised flowers. | Eflornithine | ornithine decarboxylase | Nicotiana tabacum |
2 | In vivo inhibition of ODC with DFMO resulted in a significant decrease in PA titers, ovary fresh weight and protein content. | Eflornithine | ornithine decarboxylase | Nicotiana tabacum |
3 | Simultaneous inhibition of both decarboxylases by DFMO and DFMA produced only a marginally greater depression in growth and PA titers, indicating that ODC activity is rate-limiting for PA biosynthesis in these tissues. | Eflornithine | ornithine decarboxylase | Nicotiana tabacum |
4 | In vivo inhibition of ODC by DFMA appears to result from arginase-mediated hydrolysis of this inhibitor to urea and DFMO, the suicide substrate for ODC. | Eflornithine | ornithine decarboxylase | Nicotiana tabacum |
5 | In vivo inhibition of ODC by DFMA appears to result from arginase-mediated hydrolysis of this inhibitor to urea and DFMO, the suicide substrate for ODC. | Eflornithine | ornithine decarboxylase | Nicotiana tabacum |
