Reaction: 2-hydroxy-5-(methylsulfanyl)-3-oxopent-1-enyl phosphate + H2O = 1,2-dihydroxy-5-(methylsulfanyl)pent-1-en-3-one + phosphate
Other name(s): HK-MTPenyl-1-P phosphatase; MtnX; YkrX; 2-hydroxy-5-(methylthio)-3-oxopent-1-enyl phosphate phosphohydrolase
Systematic name: 2-hydroxy-5-(methylsulfanyl)-3-oxopent-1-enyl phosphate phosphohydrolase
Comments: The enzyme participates in the methionine salvage pathway in Bacillus subtilis [2]. In some species a single bifunctional enzyme, EC 3.1.3.77, acireductone synthase, catalyses both this reaction and EC 5.3.2.5, 2,3-diketo-5-methylthiopentyl-1-phosphate enolase [1].
