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;
