|UDP-N-acetylglucosamine 2-epimerase (hydrolyzing).
|UDP-N-acetyl-alpha-D-glucosamine + H(2)O <=> 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.
- It catalyzes the first step of sialic acid (N-acetylneuraminic acid)
- The initial product formed is the alpha anomer, which rapidly
mutarotates to a mixture of anomers.
- The mammalian enzyme is bifunctional and also catalyzes EC 126.96.36.199.
- Cf. EC 188.8.131.52.
