Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF02919 Topoisom_I_N Eukaryotic DNA topoisomerase I, DNA binding fragment Family
A PF14370 Topo_C_assoc C-terminal topoisomerase domain Family
A PF01028 Topoisom_I Eukaryotic DNA topoisomerase I, catalytic core Domain Topoisomerase I promotes the relaxation of DNA superhelical tension by introducing a transient single-stranded break in duplex DNA and are vital for the processes of replication, transcription, and recombination [2].
