CC -!- FUNCTION: Catalyzes 2 different reactions between oxygen and the
CC acireductone 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene)
CC depending upon the metal bound in the active site. Fe-containing
CC acireductone dioxygenase (Fe-ARD) produces formate and 2-keto-4-
CC methylthiobutyrate (KMTB), the alpha-ketoacid precursor of methionine
CC in the methionine recycle pathway. Ni-containing acireductone
CC dioxygenase (Ni-ARD) produces methylthiopropionate, carbon monoxide and
CC formate, and does not lie on the methionine recycle pathway.
CC {ECO:0000256|HAMAP-Rule:MF_03154}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + O2 = 3-
CC (methylsulfanyl)propanoate + CO + formate + 2 H(+);
CC Xref=Rhea:RHEA:14161, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,
CC ChEBI:CHEBI:15740, ChEBI:CHEBI:17245, ChEBI:CHEBI:49016,

CC Rule:MF_03154};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + O2 = 4-
CC methylsulfanyl-2-oxobutanoate + formate + 2 H(+);
CC Xref=Rhea:RHEA:24504, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,
CC ChEBI:CHEBI:15740, ChEBI:CHEBI:16723, ChEBI:CHEBI:49252;
CC EC=1.13.11.54; Evidence={ECO:0000256|ARBA:ARBA00000428,
CC ECO:0000256|HAMAP-Rule:MF_03154};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03154};
CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03154};
CC Note=Binds either 1 Fe or Ni cation per monomer. Iron-binding promotes
CC an acireductone dioxygenase reaction producing 2-keto-4-
CC methylthiobutyrate, while nickel-binding promotes an acireductone
CC dioxygenase reaction producing 3-(methylsulfanyl)propanoate.
CC {ECO:0000256|HAMAP-Rule:MF_03154};
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via salvage
CC pathway; L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate:
CC step 5/6. {ECO:0000256|HAMAP-Rule:MF_03154}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03154}.
CC Nucleus {ECO:0000256|HAMAP-Rule:MF_03154}.
CC -!- SIMILARITY: Belongs to the acireductone dioxygenase (ARD) family.
CC {ECO:0000256|HAMAP-Rule:MF_03154}.
