Purification and Characterization of the Main Isozyme of Polyphenol Oxidase in Mung Bean (Vigna mungo) Seedlings.
Pe]ypheno] oxidase (monophenol dLhydrexyphenylalanine' oxygen ox]doTeductase/ EC 1 14.1S t; PPO) hus been found in most higher plunts. although its ro]e has not yet becn clearly cstab]]shed. When the extracts frem var]ous organs of' mung bean seedlings were unalyzecl by :soelectric f'ocustng, several bancls of PPO ttet]vity were dctectcd. Among these isozyrnes, the one with pl S,4 showed the hi...
متن کاملEffect of Anti Browning Agents on Partial Purified Polyphenol Oxidase of Hawthorn (Crataegus Spp
Objective: Polyphenol oxidase or PPO (EC 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. The objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of Cysteine, Ascorbic acid, citric acid, kojic acid and glycine at two different pH (6 and 7) in hawthorn. Me...

متن کاملMicroheterogeneity in purified broad bean polyphenol oxidase.
Polyphenoloxidase was purified from chloroplasts of broad bean leaves (Vicia faba L.) to apparent homogeneity. The enzyme was composed of two proteins with an apparent mass of 65 and 68 kilodaltons after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The isolated enzyme contained covalently attached carbohydrates and bound concanavalin A, Phaseolus vulgaris erythroagglutinin, and Ri...
متن کاملDirect Electrochemistry of Polyphenol Oxidase
The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
