case <FTGroup:1> and <OC:Mammalia>
FUNCTIONCatalyzes 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. Also down- regulates cell migration mediated by MMP14.

case <FTGroup:1>
CATALYTIC ACTIVITY Reaction=1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + O2 = 4- methylsulfanyl-2-oxobutanoate + formate + 2 H(+); Xref=Rhea:RHEA:24504, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:15740, ChEBI:CHEBI:16723, ChEBI:CHEBI:49252; EC=1.13.11.54;
CATALYTIC ACTIVITY Reaction=1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + O2 = 3- (methylsulfanyl)propanoate + CO + formate + 2 H(+); Xref=Rhea:RHEA:14161, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:15740, ChEBI:CHEBI:17245, ChEBI:CHEBI:49016, ChEBI:CHEBI:49252; EC=1.13.11.53;
COFACTOR Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Name=Ni(2+); Xref=ChEBI:CHEBI:49786; Note=Binds either 1 Fe or Ni cation per monomer. Iron-binding promotes an acireductone dioxygenase reaction producing 2-keto-4- methylthiobutyrate, while nickel-binding promotes an acireductone dioxygenase reaction producing 3-(methylsulfanyl)propanoate.;
PATHWAYAmino-acid biosynthesis; L-methionine biosynthesis via salvage pathway; L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate: step 5/6.
end case
case <OC:Mammalia>
SUBUNITMonomer. Interacts with MMP14.
SUBCELLULAR LOCATIONCytoplasm. Nucleus. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Note=Localizes to the plasma membrane when complexed to MMP14.
else case <OC:Vertebrata> and not <OC:Mammalia>
SUBUNITMonomer.
SUBCELLULAR LOCATIONCytoplasm. Nucleus. Cell membrane; Peripheral membrane protein; Cytoplasmic side.
else
SUBCELLULAR LOCATIONCytoplasm. Nucleus.
end case
SIMILARITYBelongs to the acireductone dioxygenase (ARD) family.
case not <FTGroup:1>
FUNCTIONProbable inactive acireductone dioxygenase.
CAUTIONThis enzyme lacks one or more conserved metal-binding sites. It may be non-functional.
