Abstract

The carbohydrate-binding domain (CBD) is a short domain found in many different glycosyl hydrolase enzymes, such as the C-terminal cellulose-binding domain of endoglucanase Z [PubMed9405041]. The domain has a core structure consisting of a 3-stranded meander beta-sheet, which contains six aromatic groups that may be important for binding.

The overall topology of the CBD is structurally similar to the C-terminal chitin-binding domains (ChBD) of chitinase A1 and chitinase B, however the binding mechanism for the ChBD may be different from that of the CBD [PubMed10788483].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


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 Carbohydrate 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 Carbohydrate binding domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
