MetaCyc Pathway: chrysin biosynthesis

This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.

Superclasses: Biosynthesis Secondary Metabolites Biosynthesis Phenylpropanoid Derivatives Biosynthesis Flavonoids Biosynthesis Flavonols Biosynthesis

Some taxa known to possess this pathway include ? : Petroselinum crispum

Expected Taxonomic Range: Apiaceae

Summary:
Chrysin is an alternative product of reactions utilizing pinocembrin. Pinobanksin is also produced from pinocembrin. Intermediates prior to pinocembrin are equivalent for chrysin and pinobanksin, though they have been characterized in different organisms.
