LyasesOpen in Browse
CatLog read 38 records for EC 4.2.1.92 from 2 papers, for 5 organisms. Names in these papers: allene oxide synthase (CYP74A1), CYP74C13_MT hydroperoxide lyase/epoxyalcohol synthase (HPL/EAS, CYP74C), CYP74C1_CS hydroperoxide lyase/epoxyalcohol synthase (HPL/EAS, CYP74C), CYP74C31 hydroperoxide lyase/epoxyalcohol synthase (HPL/EAS, CYP74C) and 2 more.
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 10 records for EC 4.2.1.92 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 4.2.1.92 in Browse.
