EC 5.5.1.7 Chloromuconate cycloisomerase. [4 PDB entries]    
1chr

Pathway: Muconate Cycloisomerase
Reaction: 2-chloro-2,5-dihydro-5-oxofuran-2-acetate = 3-chloro-cis,cis-muconate.
 


2-chloro-2,5-dihydro-5-oxofuran-2-acetate
=
3-chloro-cis,cis-muconate
Molecule diagrams generated from .mol files obtained from the KEGG ftp site.

Other name(s): Muconate cycloisomerase Ii.
Cofactor(s): Mn(2+).
Comments: Spontaneous elimination of HCl produces cis-4-carboxymethylenebut-2- en-4-olide. Also acts in reverse direction on 2-chloro-cis,cis-muconate. Not identical with Ec 5.5.1.1 or Ec 5.5.1.11.
