Description2-Oxo-3-hydroxy-4-phosphobutanoic acid, also known as (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate or alpha-keto-3-hydroxy-4-phosphobutyrate, belongs to the class of organic compounds known as short-chain keto acids and derivatives. These are keto acids with an alkyl chain the contains less than 6 carbon atoms. 2-Oxo-3-hydroxy-4-phosphobutanoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Oxo-3-hydroxy-4-phosphobutanoic acid exists in all living species, ranging from bacteria to humans. Within yeast, 2-oxo-3-hydroxy-4-phosphobutanoic acid participates in a number of enzymatic reactions. In particular, 2-oxo-3-hydroxy-4-phosphobutanoic acid can be biosynthesized from 4-phospho-D-erythronate; which is catalyzed by the enzyme erythronate-4-phosphate dehydrogenase. In addition, 2-oxo-3-hydroxy-4-phosphobutanoic acid and L-glutamic acid can be converted into O-phospho-4-hydroxy-L-threonine and oxoglutaric acid through the action of the enzyme 3-phosphoserine aminotransferase / phosphohydroxythreonine aminotransferase. In yeast, 2-oxo-3-hydroxy-4-phosphobutanoic acid is involved in the metabolic pathway called the vitamin B6 pathway.
