N-acetylneuraminate epimerase

N-acetylneuraminate epimerase (, sialic acid epimerase, N-acetylneuraminate mutarotase, sialic acid mutarotase, YjhT, NanM) is an enzyme with systematic name N-acetyl-alpha-neuraminate 2-epimerase. This enzyme catalyses the following chemical reaction


 * N-acetyl-alpha-neuraminate $$\rightleftharpoons$$ N-acetyl-beta-neuraminate
