| 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 | Reaction=S-methyl-5-thio-D-ribulose 1-phosphate = 5-methylsulfanyl-2,3- dioxopentyl phosphate + H2O; Xref=Rhea:RHEA:15549, ChEBI:CHEBI:15377, ChEBI:CHEBI:58548, ChEBI:CHEBI:58828; EC=4.2.1.109; |
| COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; 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. |
