UDP-N-acetylglucosamine 2-epimerase (hydrolysing) (EC 3.2.1.183, UDP-N-acetylglucosamine 2-epimerase, GNE (gene), siaA (gene), neuC (gene)) is an enzyme with systematic name UDP-N-acetyl-alpha-D-glucosamine hydrolase (2-epimerising).[1][2][3][4] This enzyme catalyses the following chemical reaction
- UDP-N-acetyl-alpha-D-glucosamine + H2O N-acetyl-D-mannosamine + UDP
The enzyme is found in mammalian liver, as well as in some pathogenic bacteria including Neisseria meningitidis and Staphylococcus aureus.
