catalytic activity:5-(methylthio)-2,3-dioxopentyl phosphate + H(2)O = 1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + phosphate.,cofactor:Binds 1 magnesium ion per subunit.,function:Bifunctional enzyme that enolizes the substrate to form the intermediate 2-hydroxy-5-(methylthio)-3-oxopent-1-enyl phosphate, which is then dephosphorylated to form the acireductone 1,2-dihydroxy-5-(methylthio)pent-1-en-3-one.,pathway:Amino-acid biosynthesis; L-methionine biosynthesis via salvage pathway; L-methionine from (S)-methyl-5-thio-alpha-D-ribose 1-phosphate: step 3/6.,pathway:Amino-acid biosynthesis; L-methionine biosynthesis via salvage pathway; L-methionine from (S)-methyl-5-thio-alpha-D-ribose 1-phosphate: step 4/6.,similarity:Belongs to the HAD-like hydrolase superfamily. MasA/mtnC family.,subunit:Monomer.,
