title: Informations on the active site of palmito polyphenol oxidase.
abstract: pH studies of palmito polyphenol oxidase are carried out with either 4-methylcatechol or pyrogallol as substrates. The pH profile is independent of the nature of the substrates tested. The symmetrical behaviour and the very slight differences between the values obtained suggest the existence of only one site on the molecule for o-diphenol substrates.
