Type II DNA topoisomerases are ubiquitous enzymes that catalyse the ATP-dependent transport of one DNA duplex through a second DNA segment via a transient double-strand break. Type II DNA topoisomerases are now subdivided into two sub-families, type IIA and IIB DNA topoisomerases. TP6A_N is present in type IIB topoisomerase and is thought to be involved in DNA binding owing to its sequence similarity to E. coli catabolite activator protein (CAP) [1].	Domain

This topoisomerase-primase (Toprim) nucleotidyl transferase/hydrolase domain is found in the type II topoisomerase VIA and Spo11, which structurally related. Spo11 is a meiosis-specific protein that is responsible for the initiation of recombination through the formation of DNA double-strand breaks by a type II DNA topoisomerase-like activity. Topoisomerase VI is a type IIB enzyme that breaks double-stranded DNA and assembles as a heterotetramer, consisting of two A subunits required for DNA cleavage and two B subunits required for ATP hydrolysis [1-3].
