STUDIES ON GLYCOLLATE OXIDASE FROM PEA LEAVES DETERMINATION OF STEREOSPECIFICITY AND MODE OF INHIBITION BY a-HYDROXYBUTYNOATE
Glycollate oxidase (glycollate:oxygen oxidoreductase, EC 1.1.3.1) from Pisum .f>ativum has an unusual absorption spectrum which suggests that the flavin N(3)-H function of the FMN coenzyme is ionized at pH 8.3. The enzyme is reduced rapidly by the substrate glycollate to yield a normal, reduced FMN coenzyme which is readily reoxidized by Oz. No evidence for the occurrence of covalent intermedia...
متن کاملInhibition of monoamine oxidase by stilbenes from Rheum palmatum
Seven stilbenes and one catechin were bioactivity-guidedly isolated from the rhizomes of Rheum palmatem. Their structures were identified as piceatannol(1), resveratrol(2), piceid(3), rhapontigenin(4), piceatannol-3'-O-β-D-glucopyranoside(5), rhaponticin(6), catechin(7) and desoxyrhapontigenin(8). Anti-monoamine oxidase (MAO) activities of compounds 1–8 were tested. Compounds 1 and 8 showed sig...

متن کاملPhysicochemical characterization of mitochondrial DNA from pea leaves.
The mitochondrial DNA from pea leaves exists in a circular conformation. 25% of the circular molecules exist as supercoils, and 10% of the molecules are dimers. The molecular weight of mitochondrial DNA is about 66 to 70 x 10(6) by electron microscopy, and 74 x 10(6) from its renaturation kinetics. No evidence for inter- and intramolecular heterogeneity is found.
