Characterization of an isoflavonoid-specific prenyltransferase from Lupinus albus.
Prenylated flavonoids and isoflavonoids possess antimicrobial activity against fungal pathogens of plants. However, only a few plant flavonoid and isoflavonoid prenyltransferase genes have been identified to date. In this study, an isoflavonoid prenyltransferase gene, designated as LaPT1, was identified from white lupin (Lupinus albus). The deduced protein sequence of LaPT1 shared high homologi...

متن کاملFungitoxic Isoflavones from Lupinus albus and other Lupinus Species
Leguminosae, Papilionoideae, Lupinus, Lupins, Isoflavonoids, Isoflavones, Phenolic Compounds, Antifungal Activity The constitutive isoflavones genistein, 2'-hydroxygenistein, wighteone and luteone have been isolated in varying amounts from methanolic leaf washings of eight species belonging to the legume genus Lupinus. These four compounds likewise occur in the flower buds, stems, roots and imm...
متن کاملCharacterization of aspartate aminotransferase isoenzymes from leaves of Lupinus albus L. cv Estoril.
Two aspartate aminotransferase (EC 2.6.1.1) isoenzymes (AAT-1 and AAT-2) from Lupinus albus L. cv Estoril were separated, purified, and characterized. The molecular weight, pI value, optimum pH, optimum temperature, and thermodynamic parameters for thermal inactivation of both isoenzymes were obtained. Studies of the kinetic mechanism, and the kinetics of product inhibition and high substrate c...
