Name1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
Description1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate, also known as 1-[(2-carboxyphenyl)amino]-1-deoxy-5-O-phosphono-D-ribulose, belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate exists in both E. coli (prokaryote) and yeast (eukaryote). 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate can be biosynthesized from N-(5-phosphoribosyl)-anthranilate through its interaction with the enzyme N-(5'-phosphoribosyl)anthranilate isomerase. In yeast, 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate is involved in the metabolic pathway called the tryptophan metabolism pathway.
