DE   Acireductone dioxygenase (Fe(2+)-requiring).
AN   2-hydroxy-3-keto-5-thiomethylpent-1-ene dioxygenase.
AN   Acireductone dioxygenase.
AN   ARD'.
AN   E-2'.
CA   1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + O(2) = 4-(methylthio)-2-
CA   oxobutanoate + formate.
CF   Fe(2+).
CC   -!- If Ni(2+) is bound instead of Fe(2+), the reaction catalyzed by
CC       EC 1.13.11.53 occurs instead.
CC   -!- The enzyme from Klebsiella oxytoca (formerly Klebsiella pneumoniae)
CC       ATCC 8724 is involved in the methionine salvage pathway.
