Escherichia coli K-12 substr. MG1655 Enzyme: oxalyl-CoA decarboxylase

Gene: oxc Accession Numbers: G7236 (EcoCyc), b2373, ECK2369

Synonyms: yfdU

Regulation Summary Diagram: ?

Subunit composition of oxalyl-CoA decarboxylase = [Oxc]4
         oxalyl-CoA decarboxylase = Oxc

Oxc is the E. coli ortholog of the oxalyl-CoA decarboxylase from Oxalobacter formigenes. The enzyme has oxalyl-CoA decarboxylase activity and may be used for oxalate detoxification [Werther10].

Crystal structures of the apoenzyme and in complex with ADP or the substrate analog acetyl-CoA have been solved. The crystal structure indicates that the enzyme is a tetramer assembled as a dimer of dimers [Werther10].

Oxc is required during the adaption phase of an oxalate-induced acid tolerance response [Fontenot13].
