Fig. 1From: Molecular genetics of naringenin biosynthesis, a typical plant secondary metabolite produced by Streptomyces clavuligerus Proposed naringenin biosynthesis pathway in S. clavuligerus. The names of the intermediate compounds, enzymes involved and genes are indicated. Naringenin biosynthesis starter in plants is usually phenylalanine and there are additional steps for the hydroxylation of cinnamic acid to produce p-coumaroic acidBack to article page
