'''Muconate cycloisomerase''' (MCI) catalyzes the formation of muconolactone from cis, cis-muconate. It is part of the B-ketoadipate pathway in the metabolism of aromatic compounds. | '''Muconate cycloisomerase''' (MCI) catalyzes the formation of muconolactone from ''cis,cis''-muconate. It is part of the B-ketoadipate pathway in the metabolism of aromatic compounds<ref>PMID:9726873</ref>. MCI breaks down lignin-derived catechol and protocatechuate. | ||
