The enzyme methylthioribulose 1-phosphate dehydratase (EC .2.1.109) catalyzes the chemical reaction
- 5-(methylsulfanyl)-D)ribulose 1-phosphate [math]\displaystyle{ \rightleftharpoons }[/math] 5-(methylthio)-2,3-dioxopentyl phosphate + H2
This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 5-methyl-5-thio-D-ribulose-1-phosphate 4-hydro-lyase [5-(methylthio)-2,3-dioxopentyl-phosphate-forming]. Other names in common use include 1-PMT-ribulose dehydratase, and S-methyl-5-thio-D-ribulose-1-phosphate hydro-lyase. This enzyme participates in methionine metabolism.
