N-acetylneuraminate synthase
Template:Short description Template:Infobox enzyme In enzymology, a N-acetylneuraminate synthase (EC 2.5.1.56) is an enzyme that catalyzes the chemical reaction
- phosphoenolpyruvate + N-acetyl-D-mannosamine + H2O phosphate + N-acetylneuraminate
The 3 substrates of this enzyme are phosphoenolpyruvate, N-acetyl-D-mannosamine, and H2O, whereas its two products are phosphate and N-acetylneuraminate.
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-acetyl-D-mannosamine C-(1-carboxyvinyl)transferase (phosphate-hydrolysing, 2-carboxy-2-oxoethyl-forming). Other names in common use include (NANA)condensing enzyme, N-acetylneuraminate pyruvate-lyase (pyruvate-phosphorylating), and NeuAc synthase. 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.
