Protein

Acireductone dioxygenase

Gene

mtnD

Organism
Parvibaculum lavamentivorans (strain DS-1 / DSM 13023 / NCIMB 13966)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

Catalyzes 2 different reactions between oxygene 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.UniRule annotation

Catalytic activityi

1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + O2 = 3-(methylthio)propanoate + formate + CO.UniRule annotation
1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + O2 = 4-(methylthio)-2-oxobutanoate + formate.UniRule annotation

Cofactori

Protein has several cofactor binding sites:
  • Fe cationUniRule annotationNote: Binds 1 Fe cation per monomer.UniRule annotation
  • Ni2+UniRule annotationNote: Binds 1 nickel ion per monomer.UniRule annotation
