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].

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

You can use the tree controls to manipulate how the interactive tree is displayed:
- show/hide the summary boxes
- highlight species that are represented in the seed alignment
- expand/collapse the tree or expand it to a given depth
- select a sub-tree or a set of species within the tree and view them graphically or as an alignment
- save a plain text representation of the tree
There are 3 interactions for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
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 domain has been found. There are 103 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.
