Biochemical studies of cocoa bean polyphenol oxidase
Polyphenol oxidase (EC 1.14.18.1) was isolated and partially purified from cocoa beans. The properties of the enzyme were studied. The Michaelis constant Km for catechol was 1 × 10−2 M. The pH optimum of polyphenol oxidase activity assayed with catechol as substrate occurred at pH 6.8 and was charac...
