DNA topoisomerases are essential for DNA metabolism and while their role is well studied in prokaryotes and eukaryotes, it is less known for virally-encoded topoisomerases. African swine fever virus (ASFV) is a nucleo-cytoplasmic large DNA virus that infects Ornithodoros ticks and all members of the family Suidae, representing a global threat for pig husbandry with no effective vaccine nor treatment...
Topoisomerases modulate the topological state of DNA during processes, such as replication and transcription, that cause overwinding and/or underwinding of the DNA. African swine fever virus (ASFV) is a nucleo–cytoplasmic double-stranded DNA virus shown to contain an OFR (P1192R) with homology to type II topoisomerases. Here we observed that pP1192R is highly conserved among ASFV isolates but dissimilar...
