FunFam 13: Bifunctional UDP-N-acetylglucosamine 2-epimerase/N...

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
N-acylmannosamine kinase. [EC: 2.7.1.60]
ATP + N-acyl-D-mannosamine = ADP + N-acyl-D-mannosamine 6-phosphate.
  • Acts on the acetyl and glycolyl derivatives.

UDP-N-acetylglucosamine 2-epimerase (hydrolyzing). [EC: 3.2.1.183]
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) biosynthesis.
  • 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 2.7.1.60.
  • Cf. EC 5.1.3.14.
