IsomerasesOpen in Browse

CatLog read 37 records for EC 5.3.2.6 from 4 papers, for 4 organisms. Names in these papers: heterohexamer 4-oxalocrotonate tautomerase (hh4-OT), 4-oxalocrotonate tautomerase (Pp 4-OT), YwhB (4-oxalocrotonate tautomerase homologue), DmpI (AfDmpI, 4-oxalocrotonate tautomerase homologue, subfamily 4).

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 71 records for EC 5.3.2.6 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 5.3.2.6 in Browse.
