Protein

1,2-dihydroxy-3-keto-5-methylthiopentene dioxygenase

Gene

Npun_R2028

Organism
Nostoc punctiforme (strain ATCC 29133 / PCC 73102)
Status
Unreviewed-Annotation score: Annotation score: 2 out of 5-Protein predictedi

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.SAAS annotation

Catalytic activityi

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

Cofactori

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