FunFam 96486: Similar to UDP-N-acetylglucosamine 2-epimerase

There are 3 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
UDP-N-acetylglucosamine 2-epimerase (non-hydrolyzing). [EC: 5.1.3.14]
UDP-N-acetyl-alpha-D-glucosamine = UDP-N-acetyl-alpha-D-mannosamine.
  • This bacterial enzyme catalyzes the reversible interconversion of UDP-GlcNAc and UDP-ManNAc.
  • The latter is used in a variety of bacterial polysaccharide biosyntheses.
  • Cf. EC 3.2.1.183.

UDP-2,3-diacetamido-2,3-dideoxyglucuronic acid 2-epimerase. [EC: 5.1.3.23]
UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-glucuronate = UDP-2,3- diacetamido-2,3-dideoxy-alpha-D-mannuronate.
  • Participates in the biosynthetic pathway for UDP-alpha-D-ManNAc3NAcA (UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-mannuronic acid), an important precursor of the B-band lipopolysaccharide of Pseudomonas aeroginosa serotype O5 and of the band-A trisaccharide of Bordetella pertussis, both important respiratory pathogens.
  • Highly specific as UDP-alpha-D-GlcNAc, UDP-alpha-D-GlcNAcA (UDP-2- acetamido-2-deoxy-alpha-D-glucuronic acid) and UDP-alpha-D-GlcNAc3NAc (UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-glucose) cannot act as substrates.

UDP-glucose 6-dehydrogenase. [EC: 1.1.1.22]
UDP-glucose + 2 NAD(+) + H(2)O = UDP-glucuronate + 2 NADH.
  • Also acts on UDP-2-deoxyglucose.
