In enzymology, a N-acylneuraminate-9-phosphate synthase (EC 2.5.1.57) is an enzyme that catalyzes the chemical reaction

phosphoenolpyruvate + N-acyl-D-mannosamine 6-phosphate + H2O N-acylneuraminate 9-phosphate + phosphate

The 3 substrates of this enzyme are phosphoenolpyruvate, N-acyl-D-mannosamine 6-phosphate, and H2O, whereas its two products are N-acylneuraminate 9-phosphate and phosphate.

This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is phosphoenolpyruvate:N-acyl-D-mannosamine-6-phosphate 1-(2-carboxy-2-oxoethyl)transferase. Other names in common use include N-acetylneuraminate 9-phosphate lyase, N-acetylneuraminate 9-phosphate sialic acid 9-phosphate synthase, N-acetylneuraminate 9-phosphate synthetase, N-acylneuraminate-9-phosphate pyruvate-lyase, (pyruvate-phosphorylating), and sialic acid 9-phosphate synthetase. This enzyme participates in aminosugars metabolism.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1WVO.

3-Deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) synthase is the first enzyme in a series of metabolic reactions known as the shikimate pathway, which is responsible for the biosynthesis of the amino acids phenylalanine, tyrosine, and tryptophan. Since it is the first enzyme in the shikimate pathway, it controls the amount of carbon entering the pathway. Enzyme inhibition is the primary method of regulating the amount of carbon entering the pathway. Forms of this enzyme differ between organisms, but can be considered DAHP synthase based upon the reaction that is catalyzed by this enzyme.
