Description | 5-(Methylthio)-2,3-dioxopentyl phosphate, also known as 1-phospho-2,3-diketo-5-S-methylthiopentane or 2,3-diketo-5-methylthio-1-phosphopentane, belongs to the class of organic compounds known as monoalkyl phosphates. These are organic compounds containing a phosphate group that is linked to exactly one alkyl chain. 5-(Methylthio)-2,3-dioxopentyl phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). Within yeast, 5-(methylthio)-2,3-dioxopentyl phosphate participates in a number of enzymatic reactions. In particular, 5-(methylthio)-2,3-dioxopentyl phosphate can be converted into 1,2-dihydroxy-3-keto-5-methylthiopentene through the action of the enzyme 2,3-dioxomethiopentane-1-phosphate enolase/phosphatase. In addition, 5-(methylthio)-2,3-dioxopentyl phosphate can be biosynthesized from 5-methylthioribulose 1-phosphate through its interaction with the enzyme methylthioribulose-1-phosphate dehydratase. In yeast, 5-(methylthio)-2,3-dioxopentyl phosphate is involved in the metabolic pathway called the methionine metabolism and salvage pathway. |
