Purification and Characterization of Two Isolectins with Arginase Activity from the Lichen Xanthoria parietina
Two glycoproteins were purified and biochemically characterized from the lichen X. parietina. Both behaved as enzymes with arginase activity and haemaglutinins. Secreted arginase (SA) contained galactose and glucose in the saccharide moiety and an isoelectric point of 4.54. The algal binding-protein (ABP) had N-acetyl-glucosamine and glucose as glycosidic residues and an isoelectric point of 3....
متن کاملThe bromoperoxidase from the lichen Xanthoria parietina is a novel vanadium enzyme.
A novel bromoperoxidase was isolated from the lichen Xanthoria parietina. The enzyme contained vanadium, which is essential for enzymic activity. Under denaturating conditions the preparation showed a single protein band with an Mr of 65,000. Thermal-denaturation studies showed that this bromoperoxidase could tolerate high temperatures. The affinity of the enzyme for its substrate bromide is hi...
متن کاملAntiproliferative, Antibacterial and Antifungal Activity of the Lichen Xanthoria parietina and Its Secondary Metabolite Parietin
Lichens are valuable natural resources used for centuries throughout the world as medicine, food, fodder, perfume, spices and dyes, as well as for other miscellaneous purposes. This study investigates the antiproliferative, antibacterial and antifungal activity of the acetone extract of the lichen Xanthoria parietina (Linnaeus) Theodor Fries and its major secondary metabolite, parietin. The ext...
