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_03117}.
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 Nucleus {ECO:0000255|HAMAP-Rule:MF_03117}.
CC -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. MasA/MtnC
CC family. {ECO:0000255|HAMAP-Rule:MF_03117}.
