Abstract

Topoisomerase strand cleavage involves nucleophilic attack by a catalytic tyrosine residue, resulting in the enzyme being covalently attached to one end of the broken DNA strand. Eukaryotic DNA topoisomerase I is a multi-domain protein. The dispensable insert domain is the linker region that connects the central core of the enzyme to the C-terminal domain; it assumes a coiled-coil configuration and protrudes away from the remainder of the enzyme [PubMed9488652].

More information about this protein can be found at Protein of the Month: DNA Topoisomerase.

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 1 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 Eukaryotic DNA topoisomerase I, dispensable insert 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 1 hidden Markov models representing the Eukaryotic DNA topoisomerase I, dispensable insert domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
