Abstract

This entry represents the N-terminal effector-binding domain of the type II restriction endonuclease EcoRII, which has a DNA recognition fold, allowing for binding to 5'-CCWGG sequences. It assumes a structure composed of an eight-stranded beta-sheet with the strands in the order of b2, b5, b4, b3, b7, b6, b1 and b8. They are mostly antiparallel to each other except that b3 is parallel to b7. Alternatively, it may also be viewed as consisting of two mini beta-sheets of four antiparallel beta-strands, sheet I from beta-strands b2, b5, b4, b3 and sheet II from strands b7, b6, b1, b8, folded into an open mixed beta-barrel with a novel topology. Sheet I has a simple Greek key motif while sheet II does not [PubMed14659759].

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