Muconate lactonizing enzymes (EC 5.5.1.1 muconate cycloisomerase I ciscis-muconate-lactonizing enzyme ciscis-muconate cycloisomerase 4-carboxymethyl-4-hydroxyisocrotonolactone lyase (decyclizing) CatB MCI MLE 25-dihydro-5-oxofuran-2-acetate lyase (decyclizing)) are involved in the breakdown of lignin-derived aromatics catechol and protocatechuate to citric acid cycle intermediates as a part of the β-ketoadipate pathway in soil microbes.
