Summary: Family 31 carbohydrate binding protein
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
Family 31 carbohydrate binding protein Provide feedback
This family of proteins represents the family 31 carbohydrate-binding module of beta-1,2-xylanase. This protein is from Alcaligenes sp. strain XY-234. The AlcCBM31 module makes a beta-sandwich structure with an immunoglobulin fold and contains two intra-molecular disulfide bonds. AlcCBM31 shows affinity with only beta-1,3-xylan .

Beta-1,3-xylan is a homopolymer of b-1,3-linked D-xylose and is a polysaccharide peculiar to marine algae. Beta-1,3-xylanase is a beta-1,3-xylan hydrolyzing enzyme [PUBMED:10742274].

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 UniProtKB sequence database using the family HMM
- 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:

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

There is 1 interaction 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 AlcCBM31 domain has been found. There are 6 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.
