Abstract

Beta barrels are commonly observed in protein structures. They are classified in terms of two integral parameters: the number of strands in the sheet, n, and the shear number, S, a measure of the stagger of the strands in the beta-sheet. These two parameters have been shown to determine the major geometrical features of beta-barrels. Six-stranded beta-barrels with a pseudo-twofold axis are found in several proteins. One involving parallel strands forming two psi structures is known as the double-psi barrel. The first psi structure consists of the loop connecting strands beta1 and beta2 (a 'psi loop') and the strand beta5, whereas the second psi structure consists of the loop connecting strands beta4 and beta5 and the strand beta2. All the psi structures in double-psi barrels have a unique handedness, in that beta1 (beta4), beta2 (beta5) and the loop following beta5 (beta2) form a right-handed helix. The unique handedness may be related to the fact that the twisting angle between the parallel pair of strands is always larger than that between the antiparallel pair [PubMed10368289].

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 13 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 Barwin-like endoglucanases 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 13 hidden Markov models representing the Barwin-like endoglucanases superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
