L-Tyrosine biosynthesis via two pathways in plants and microbes. Two pathways for Tyr biosynthesis from prephenate downstream of the shikimate pathway are shown. The PDH/TyrAp pathway is present in most microbes, whereas the ADH/TyrAa pathway is ubiquitous in plants. Tyr serves as the precursor for protein synthesis and many downstream metabolites in plants and humans.
