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).
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   -!- 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.
CC   -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. MtnX family.
