Comments [?]

Function Catalyzes the dehydration of methylthioribulose-1-phosphate (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P).
Catalytic activity RHEA:15549: S-methyl-5-thio-D-ribulose 1-phosphate = 5-methylsulfanyl-2,3-dioxopentyl phosphate + H2O
EC 4.2.1.109
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
Pathway Amino-acid biosynthesis; L-methionine biosynthesis via salvage pathway; L-methionine from S-methyl-5-thio-alpha-D-ribose 1-phosphate: step 2/6.
case <OC:Bacillaceae>
Subunit Homotetramer.
end case
Similarity Belongs to the aldolase class II family. MtnB subfamily.
