CC -!- FUNCTION: Dephosphorylates 2-hydroxy-3-keto-5-methylthiopentenyl-1-
CC phosphate (HK-MTPenyl-1-P) yielding 1,2-dihydroxy-3-keto-5-
CC methylthiopentene (DHK-MTPene). {ECO:0000255|HAMAP-Rule:MF_01680}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-hydroxy-5-methylsulfanyl-3-oxopent-1-enyl phosphate + H2O =
CC 1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + phosphate;
CC Xref=Rhea:RHEA:14481, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:49252, ChEBI:CHEBI:59505; EC=3.1.3.87;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01680};
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_01680}.
CC -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. MtnX family.
CC {ECO:0000255|HAMAP-Rule:MF_01680}.
