chloromuconate cycloisomerase  M-CSA #348

Bacterial muconate lactonizing enzymes (MLEs) catalyze the conversion of cis,cis-muconate as a part of the beta-ketoadipate pathway. Some MLEs, including the enzyme annotated here, are also able to dehalogenate chlorinated muconate to form five-member furan rings. This enzyme catalyses several cyclisation and dehalogenation reactions.
