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:0000255|HAMAP-Rule:MF_01682}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + O2 = 3-

CC -!- COFACTOR:
CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01682};
CC Note=Binds 1 nickel ion per monomer. {ECO:0000255|HAMAP-Rule:MF_01682};
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:0000255|HAMAP-Rule:MF_01682}.
