Epimerase

Epimerase
PFAM accession number:PF01370
Interpro abstract (IPR001509):

This domain is found in proteins that utilise NAD as a cofactor and use nucleotide-sugar substrates for a variety of chemical reactions [(PUBMED:9174344)]. One of the best studied of these proteins is UDP-galactose 4-epimerase which catalyses the conversion of UDP-galactose to UDP-glucose during galactose metabolism [(PUBMED:11279032), (PUBMED:10801319)].

GO function:coenzyme binding (GO:0050662), catalytic activity (GO:0003824)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Epimerase
