MetaCyc Pathway: proanthocyanidin biosynthesis from flavanols

Enzyme View:

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 Proanthocyanidins Biosynthesis

Some taxa known to possess this pathway include ? : Desmodium uncinatum , Lotus corniculatus

Expected Taxonomic Range: Tracheophyta

Summary:
Proanthocyanin biosynthesis occurs in Arabidopsis mainly in the seed coat. Proanthocyanidin is a condensed tannin, or polymeric flavonol.
