Occurence of PAL, cinnamate-hydroxylase and p-coumarate-hydroxylase, is found in cell-free extracts from Quercus pedunculata roots; moreover, an enzyme system which catalyzes benzoïc acid formation from cinnamic acid is caracterized for the first time. Role of these enzymes and their interactions within the same organ are discussed.
