Proposed divergence of the TIA pathway between Camptotheca and Catharanthus. After 7-deoxyloganic acid hydroxylase (7DLH) converts 7-deoxyloganic acid to loganic acid, the pathways in these two species diverge. The Catharanthus pathway uses loganic acid methyltransferase (LAMT) to convert loganic acid into loganin and secologanin synthase (SLS) to convert loganin into secologanin. The Camptotheca pathway bypasses LAMT and uses secologanic acid synthase (SLAS) to metabolize loganic acid directly to secologanic acid." figureDoi="http://doi.org/10.5281/zenodo.8291736" httpUri="https://zenodo.org/record/8291736/files/figure.png" pageId="3" pageNumber="4">1</figureCitation>
