WebDec 31, 2007 · As a major component of plant specialized metabolism, phenylpropanoid biosynthetic pathways provide anthocyanins for pigmentation, flavonoids such as flavones for protection against UV photodamage, various flavonoid and isoflavonoid inducers of Rhizobium nodulation genes, polymeric lignin for structural support and assorted … WebThe deamination of phenylalanine by phenylalanine ammonia lyase (PAL) first produces cinnamic acid, which serves as the precursor for all of the phenylpropanoids of secondary metabolism. A cinnamic acid 4-hydroxylase (C4H) catalyzes the introduction of a hydroxyl group at the para position of the phenyl ring of cinnamic acid, producing coumaric ...
