Acireductone dioxygenase ARD (IPR023956)

Short name: Acireductn_d0ase

Family relationships

Description

This enzyme catalyzes 2 different reactions between oxygen and the acireductone 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene) depending upon the metal bound in the active site. Fe-containing acireductone dioxygenase (Fe-ARD) produces formate and 2-keto-4-methylthiobutyrate (KMTB), the alpha-ketoacid precursor of methionine in the methionine recycle pathway. Ni-containing acireductone dioxygenase (Ni-ARD) produces methylthiopropionate,carbon monoxide and formate, and does not lie on the methionine recycle pathway. This enzyme belongs to the acireductone dioxygenase (ARD) family.
