Terpenoid portable pathway

Category：Terpenoid pathway

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

Representative Terpenoid Reaction Route
MVA/MEP precursor branches to triterpenoid scaffolds, terpene scaffolds, and tailoring. Terpenoids draw IPP/DMAPP from MVA and MEP branches before prenyl extension and TPS branching; SQS/SQE/OSC form a triterpenoid/sterol precursor layer whose overlap with the steroid library is expected.
