Araujiain aII, the protease with highest specific activity purified from latex of Araujia angustifolia (Apocynaceae), shows optimum proteolytic activity at alkaline pH, and it is completely inhibited by the irreversible inhibitor of cysteine proteases trans-epoxysucciny-L: -leucyl-amido(4-guanidino)
A new protease (araujiain h I) was purified to mass spectroscopy homogeneity from the latex of Araujia hortorum Fourn. (Asclepiadaceae) fruits by ultracentrifugation and ion exchange chromatography. The enzyme has a molecular mass of 24,031 (mass spectrometry) and an iso-electric point higher than
A crude extract rich in plant cysteine peptidases was obtained from the latex of the fruits of Araujia hortorum, a South American climbing plant. The highly concentrated extract was immobilized onto titanium dioxide to produce biocatalysts through a simple adsorption procedure. Absorbance
Two new endopeptidases were purified to homogeneity from the latex of Araujia hortorum fruits by a simple purification procedure involving ultracentrifugation and ion exchange chromatography. Molecular weights of araujiain h II and araujiain h III were 23,718 and 23546 (mass spectrometry),
