CC   -!- FUNCTION: Catalyzes the dehydration of methylthioribulose-1-phosphate
CC       (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P).
CC       Functions in the methionine salvage pathway. May play a role in
CC       apoptosis. {ECO:0000255|HAMAP-Rule:MF_03116}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=S-methyl-5-thio-D-ribulose 1-phosphate = 5-methylsulfanyl-2,3-
CC         dioxopentyl phosphate + H2O; Xref=Rhea:RHEA:15549, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:58548, ChEBI:CHEBI:58828; EC=4.2.1.109;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03116};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03116};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_03116};
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 2/6. {ECO:0000255|HAMAP-Rule:MF_03116}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03116}.
CC   -!- SIMILARITY: Belongs to the aldolase class II family. MtnB subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_03116}.
