The UDP-glucose/GDP-mannose dehydrogenases are a small group of enzymes which possesses the ability to catalyse the NAD-dependent 2-fold oxidation of an alcohol to an acid without the release of an aldehyde intermediate [PUBMED:2470755, PUBMED:9013585].
The enzymes have a wide range of functions. In plants UDP-glucose dehydrogenase, EC, is an important enzyme in the synthesis of hemicellulose and pectin [PUBMED:12031484], which are the components of newly formed cell walls; while in zebrafish UDP-glucose dehydrogenase is required for cardiac valve formation [PUBMED:11533493]. In Xanthomonas campestris, a plant pathogen, UDP-glucose dehydrogenase is required for virulence [PUBMED:11554764].
GDP-mannose dehydrogenase, EC, catalyses the formation of GDP-mannuronic acid, which is the monomeric unit from which the exopolysaccharide alginate is formed. Alginate is secreted by a number of bacteria, which include Pseudomonas aeruginosa and Azotobacter vinelandii. In P. aeruginosa, alginate is believed to play an important role in the bacteria's resistance to antibiotics and the host immune response [PUBMED:12135385], while in A. vinelandii it is essential for the encystment process [PUBMED:9864323].
This entry represents the N-terminal NAD(+)-binding domain. Structural studies indicate that this domain forms an alpha-beta structure containing the six-stranded parallel beta sheet characteristic of the dinucleotide binding Rossman fold [PUBMED:10841783, PUBMED:12705829].

A class of redox enzymes are two domain proteins. One domain, termed the catalytic domain, confers substrate specificity and the precise reaction of the enzyme. The other domain, which is common to this class of redox enzymes, is a Rossmann-fold domain. The Rossmann domain binds nicotinamide adenine dinucleotide (NAD+) and it is this cofactor that reversibly accepts a hydride ion, which is lost or gained by the substrate in the redox reaction. Rossmann domains have an alpha/beta fold, which has a central beta sheet, with approximately five alpha helices found surrounding the beta sheet.The strands forming the beta sheet are found in the following characteristic order 654123. The inter sheet crossover of the stands in the sheet form the NAD+ binding site . In some more distantly relate Rossmann domains the NAD+ cofactor is replaced by the functionally similar cofactor FAD.

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the UDPG_MGDP_dh_N domain has been found. There are 118 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
