Erythrose-4-phosphate is a phosphoric acid ester of erythrose . It is an intermediate in the pentose phosphate route (PPP).
Reactions
In carbohydrate metabolism erythrose 4-phosphate is an important intermediate. It is formed in the course of the pentose phosphate pathway under the action of the enzyme transaldolase from sedoheptulose-7-phosphate and glyceraldehyde-3-phosphate , together with fructose-6-phosphate . Plants and many microorganisms use erythrose-4-phosphate together with phosphoenolpyruvate (PEP) in the shikimic acid pathway for the synthesis of the aromatic amino acids tryptophan , tyrosine and phenylalanine . In addition, erythrose-4-phosphate can be used in plants, bacteria and fungi for the synthesis of pyridoxine , the vitamin B6.
