WebJul 2, 2014 · Volatile phenylpropenes play important roles in the mediation of interactions between plants and their biotic environments. Their biosynthesis involves the elimination of the oxygen functionality at the side-chain of monolignols and competes with lignin formation for monolignol utilization. We hypothesized that biochemical steps before the ... Webways to these and related phenylpropenes are illus-trated in Figure 1. The first committed step to the phenylpropenes, the de-amination of Phe to give cin-namic acid, is likely to be catalyzed by the well-known and widely distributed enzyme Phe ammonia lyase (PAL), just as is the case for the biosynthesis of other phenylpropanoids. human charger headphones
