Methylthioribulose 1-phosphate dehydratase

The enzyme methylthioribulose 1-phosphate dehydratase catalyzes the chemical reaction


 * 5-(methylsulfanyl)- D )ribulose 1-phosphate $$\rightleftharpoons$$ 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.
