General annotation (Comments)

Function	Bifunctional enzyme that catalyzes the enolization of 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P) into the intermediate 2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate (HK-MTPenyl-1-P), which is then dephosphorylated to form the acireductone 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene) By similarity. HAMAP MF_01681
Catalytic activity	5-(methylthio)-2,3-dioxopentyl phosphate + H2O = 1,2-dihydroxy-5-(methylthio)pent-1-en-3-one + phosphate. HAMAP MF_01681
Cofactor	Binds 1 magnesium ion per subunit By similarity. HAMAP MF_01681
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. HAMAP MF_01681 Amino-acid biosynthesis; L-methionine biosynthesis via salvage pathway; L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate: step 4/6.
Subunit structure	Monomer By similarity. HAMAP MF_01681
Sequence similarities	Belongs to the HAD-like hydrolase superfamily. MasA/mtnC family.
