Metabolite Identification
Common Name5-(Methylthio)-2,3-dioxopentyl phosphate
Description5-(Methylthio)-2,3-dioxopentyl phosphate, also known as 1-phospho-2,3-diketo-5-S-methylthiopentane or 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P), 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 slightly soluble (in water) and a moderately acidic compound (based on its pKa). 5-(Methylthio)-2,3-dioxopentyl phosphate exists in all eukaryotes, ranging from yeast to humans. 5-(Methylthio)-2,3-dioxopentyl phosphate is a metabolite involved in the cysteine and methionine metabolism pathway. It is a substrate for both E1 enolase-phosphatase and methylthioribulose-1-phosphate dehydratase. Outside of the human body, 5-(methylthio)-2,3-dioxopentyl phosphate can be found in a number of food items such as lime, pineapple, spearmint, and yautia. This makes 5-(methylthio)-2,3-dioxopentyl phosphate a potential biomarker for the consumption of these food products.

Enzymes

General function:
Involved in catalytic activity
Specific function:
Bifunctional enzyme that catalyzes the enolization of 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P) into the intermediate 2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate (HK-MTPenyl-1-P), which is then dephosphorylated to form the acireductone 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene).

General function:
Not Available
Specific function:
Catalyzes the dehydration of methylthioribulose-1-phosphate (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P). Functions in the methionine salvage pathway, which plays a key role in cancer, apoptosis, microbial proliferation and inflammation. May inhibit the CASP1-related inflammatory response (pyroptosis), the CASP9-dependent apoptotic pathway and the cytochrome c-dependent and APAF1-mediated cell death.
