Abstract

Monastrell grape polyphenol oxidase was purified, showing both activity towards monophenols and o-diphenols. The kinetic parameters, Km and optimal temperature, were evaluated in both activities. Cresolase activity presents a particular lag period, which may be modified by the temperature, enzyme concentration, the presence of o-diphenols and substrate concentration.
