CC -!- FUNCTION: Catalyzes the enolization of 2,3-diketo-5-methylthiopentyl-1-
CC phosphate (DK-MTP-1-P) into 2-hydroxy-3-keto-5-methylthiopentenyl-1-
CC phosphate (HK-MTPenyl-1-P). {ECO:0000255|HAMAP-Rule:MF_01679}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=5-methylsulfanyl-2,3-dioxopentyl phosphate = 2-hydroxy-5-
CC methylsulfanyl-3-oxopent-1-enyl phosphate; Xref=Rhea:RHEA:18769,
CC ChEBI:CHEBI:58828, ChEBI:CHEBI:59505; EC=5.3.2.5;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01679};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01679};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01679};
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 3/6. {ECO:0000255|HAMAP-Rule:MF_01679}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01679}.
CC -!- MISCELLANEOUS: Has no RuBP-carboxylation activity. {ECO:0000255|HAMAP-
CC Rule:MF_01679}.
CC -!- SIMILARITY: Belongs to the RuBisCO large chain family. Type IV
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01679}.
