Literature summary for 1.3.5.1 extracted from
- A single amino acid substitution in the SdhB protein of succinate dehydrogenase determines resistance to amicarthiazol in Xanthomonas oryzae pv. oryzae (2010), Pest Manag. Sci., 66, 627-633.
Cloned(Commentary)
| Cloned (Comment) | Organism |
|---|---|
| sdhB from mutant H229Y is ligated into a cosmid, pUFR034, to generate pUFR034RAX, which confers resistance to amicarthiazol when transformed into the wild-type sensitive strain | Xanthomonas oryzae pv. oryzae |
Protein Variants
| Protein Variants | Comment | Organism |
|---|---|---|
| H229Y | the single amino acid substitution in the SdhB protein of succinate dehydrogenase determines resistance to amicarthiazol, the mutant is insensitive to the fungicide | Xanthomonas oryzae pv. oryzae |
| additional information | several resistant mutant strains, the SDH activity of mutant strain XRUVI is clearly lower than that of wild-type strain ZJ173 in the absence of amicarthiazol, overview | Xanthomonas oryzae pv. oryzae |
Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| amicarthiazol | i.e. 2-amino-4-methylthiazole -5-carboxanilide, a systemic fungicide. The wild-type enzyme is strongly inhibited by amicarthiazol, while that in resistant mutants is insensitive. A single amino acid substitution H229Y in the SdhB protein of succinate dehydrogenase determines resistance to amicarthiazol, molecular resistance mechanism, overview; i.e. 2-amino-4-methylthiazole-5-carboxanilide, a systemic fungicide.
