Enzyme Information

1.13.11.53
Acireductone dioxygenase (Ni(2+)-requiring).
based on mapping to UniProt Q81MI9
1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + O(2) = 3-(methylthio)propanoate + formate + CO.
-!- If Fe(2+) is bound instead of Ni(2+), the reaction catalyzed by EC 1.13.11.54 occurs instead. -!- The enzyme from Klebsiella oxytoca (formerly Klebsiella pneumoniae) ATCC 8724 is involved in the methionine salvage pathway.
1.13.11.54
Acireductone dioxygenase (Fe(2+)-requiring).
based on mapping to UniProt Q81MI9
1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + O(2) = 4-(methylthio)-2- oxobutanoate + formate.
-!- If Ni(2+) is bound instead of Fe(2+), the reaction catalyzed by EC 1.13.11.53 occurs instead. -!- The enzyme from Klebsiella oxytoca (formerly Klebsiella pneumoniae) ATCC 8724 is involved in the methionine salvage pathway.
