| Abstract | The microbial degradation of cellulose and xylans requires several types of enzymes such as endoglucanases , cellobiohydrolases (exoglucanases), or xylanases [ 1886523]. Structurally, cellulases and xylanases generally consist of a catalytic domain joined to a cellulose-binding domain (CBD) by a short linker sequence rich in proline and/or hydroxy-amino acids. The CBD of a number of fungal cellulases has been shown to consist of 36 amino acid residues, and it is found either at the N-terminal or at the C-terminal extremity of the enzymes. As it is shown in the following schematic representation, there are four conserved cysteines in this type of CBD domain, all involved in disulphide bonds.

Alignments of sequences to 3 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have
different domain combinations including a Cellulose-binding domain domain.
|
Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
|
|
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
|
There are 3 hidden Markov models representing the Cellulose-binding domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
