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         Evidence={ECO:0000255|HAMAP-Rule:MF_01681};
CC       Note=Binds 1 Mg(2+) ion per subunit. {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}.
