Metabolite Identification
Common Name5-Methylthioribulose 1-phosphate
Description5-Methylthioribulose 1-phosphate, also known as 1PMT-ribulose or 1-phospho-5-S-methylthioribulose, belongs to the class of organic compounds known as glycerone phosphates. These are organic compounds containing a glycerone moiety that carries a phosphate group at the O-1 or O-2 position. 5-Methylthioribulose 1-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). 5-Methylthioribulose 1-phosphate is an intermediate in the methionine salvage pathway. 5-Methylthioribulose 1-phosphate exists in all living species, ranging from bacteria to humans. It is a microbial metabolite produced by gut microbes during methionine generation from methylthioadenosine. Outside of the human body, 5-methylthioribulose 1-phosphate has been detected, but not quantified in, several different foods, such as capers, orange mints, chicory roots, breadfruits, and asparagus. This could make 5-methylthioribulose 1-phosphate a potential biomarker for the consumption of these foods. 5-Deoxy-5-methylthioadenosine (methylthioadenosine) is a metabolite of S-adenosyl-L-methionine formed during the synthesis of the polyamines, spermidine and spermine. The first step is the phosphorolysis of methylthioadenosine to 5-methylthioribose-1-phosphate and adenine by the enzyme 5-deoxy- 5-methylthioadenosine phosphorylase (methylthioadenosine phosphorylase); 5-methylthioribose-1-phosphate is then converted to 5-methylthioribulose-1-phosphate.
