LyasesOpen in Browse
CatLog read 12 records for EC 4.2.1.139 from 1 paper, for 2 organisms. Names in these papers: GePTS1 (Glycyrrhiza echinata pterocarpan synthase 1, medicarpin-forming dirigent-like protein), PsPTS1 (Pisum sativum pterocarpan synthase 1, medicarpin-forming dirigent-like protein).
Read from the paper by an AI model and checked against the paper by a second, separate AI run; code converted the units.
CatLog also holds 2 records for EC 4.2.1.139 that are not yet re-read: from its earlier version, built from the enzyme databases and partly checked against the papers. All records for EC 4.2.1.139 in Browse.
