WebPhenylalanine and tyrosine also inhibit the second reactions of their specific pathways after chorismate, that is, the dehydratase or dehydrogenase. The primary transaminase in both phenylalanine and tyrosine synthesis is TyrB, although aspartate transaminase, AspC, can also synthesize tyrosine and phenylalanine. WebPhenylalanine is the end product of the shikimate pathway and links primary metabolism with the phenylpropanoid, flavonoid, and anthocyanin secondary metabolism pathways. This pathway is found in microorganisms and plants, but not in animals [84]. hop on bus budapest
