Phenylpropanoid portable pathway

Phenylpropanoid pathway definition imported from the 2026-05-17 portable BLAST/HMM package.

Representative Phenylpropanoid Reaction Route
Entry backbone to monolignol/lignin branches. Substrates, products, and condensed structural formulae show representative conversions; resolved reactions are shown as single enzymes, whereas multi-enzyme branches are shown as curated modules. Member counts come from public annotations.
