C [auth X] | PF09266 | Viral DNA topoisomerase I, N-terminal (VirDNA-topo-I_N) | Viral DNA topoisomerase I, N-terminal | Members of this family are predominantly found in viral DNA topoisomerase, and assume a beta(2)-alpha-beta-alpha-beta(2) fold, with a left-handed crossover between strands beta2 and beta3 [1]. | Domain |
C [auth X] | PF01028 | Eukaryotic DNA topoisomerase I, catalytic core (Topoisom_I) | Eukaryotic DNA topoisomerase I, catalytic core | 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]. | Domain |
