CC   -!- FUNCTION: Bifunctional enzyme that catalyzes the enolization of 2,3-
CC       diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P) into the
CC       intermediate 2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate (HK-
CC       MTPenyl-1-P), which is then dephosphorylated to form the acireductone
CC       1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene).
CC       {ECO:0000255|HAMAP-Rule:MF_01681}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-methylsulfanyl-2,3-dioxopentyl phosphate + H2O = 1,2-
CC         dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + phosphate;
CC         Xref=Rhea:RHEA:21700, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474,
CC         ChEBI:CHEBI:49252, ChEBI:CHEBI:58828; EC=3.1.3.77;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01681};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01681};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01681};
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 3/6. {ECO:0000255|HAMAP-Rule:MF_01681}.
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 4/6. {ECO:0000255|HAMAP-Rule:MF_01681}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01681}.
CC   -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. MasA/MtnC
CC       family. {ECO:0000255|HAMAP-Rule:MF_01681}.
