The biosynthesis of lignin, flavonoids, and hydroxycinnamoyl esters share the first three enzymatic steps of the phenylpropanoid pathway. The last shared step is catalyzed by 4-coumarate:CoA ligase (4CL), which generates p-coumaroyl CoA and caffeoyl CoA from their respective acids. Four isoforms of 4CL have been identified in Arabidopsis (Arabidopsis thaliana). Phylogenetic analysis reveals that 4CL1, 4CL2, and 4CL4 are more closely related to each other than to 4CL3, suggesting that the two… CONTINUE READING
