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