Two-state irreversible thermal denaturation of Euphorbia characias latex amine oxidase.

Bioseparation of Four Proteins from Euphorbia characias Latex: Amine Oxidase, Peroxidase, Nucleotide Pyrophosphatase/Phosphodiesterase, and Purple Acid Phosphatase

This paper deals with the purification of four proteins from Euphorbia characias latex, a copper amine oxidase, a nucleotide pyrophosphatase/phosphodiesterase, a peroxidase, and a purple acid phosphatase. These proteins, very different in molecular weight, in primary structure, and in the catalyzed reaction, are purified using identical preliminary steps of purification and by chromatographic m...

Purification and properties of two lectins from the latex of the euphorbiaceous plants Hura crepitans L. (sand-box tree) and Euphorbia characias L. (Mediterranean spurge).

1. From the latex of two members of the plant family Euphorbiaceae, Hura crepitans L. (sand-box tree) and Euphorbia characias L. (Mediterranean spurge), two lectins were purified by affinity chromatography on acid-treated Sepharose 6B followed by elution with D-galactose. 2. The lectin from E. characias is a single molecular species with Mr 80 000, made up of two identical subunits with Mr 40 0...

Acetylcholinesterase Inhibitory and Antioxidant Properties of Euphorbia characias Latex

The aim of the present study was to evaluate the acetylcholinesterase inhibitory capacity and the antioxidant properties of extracts of Euphorbia characias latex, a Mediterranean shrub. We performed a new extraction method involving the use of the trichloroacetic acid. The extract showed high antioxidant activity, was rich in total polyphenolic and flavonoid content and exhibited substantial in...

Molecular Analysis of a Copper- and Zinc-Containing Superoxide Dismutase Gene Isolated From the Latex of Euphorbia Characias: Another Piece in the Molecular Puzzle of Euphorbiaceae Latex Proteins

A copperand zinc-containing superoxide dismutase (Cu/Zn-SOD) cDNA was isolated from the Euphorbia characias latex (Elx) using consensus degenerate hybrid oligonucleotide primer (CODEHOP) design and RT-PCR strategy. Both 3’and 5’untraslated regions (UTR) were isolated by rapid amplification of cDNA ends (RACE) method. Analysis of the nucleotide sequence revealed that the Cu/Zn-SOD cDNA contains ...
