Abstract

This entry represents domains with a carbohydrate-binding-like fold, which consists of a seven-stranded beta-sandwich with a Greek key topology, although some members may have 1-2 extra strands. These domains are present as carbohydrate-binding modules in a number of glycosyl hydrolases, often at the C-terminal end, as well as in rhamnogalacturonase B (RhgB), where it occurs as a central domain [PubMed12741813, PubMed15135077].

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 9 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 Starch-binding domain-like 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 9 hidden Markov models representing the Starch-binding domain-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
