>cd01028 TOPRIM_TopoIA TOPRIM_TopoIA: topoisomerase-primase (TOPRIM) nucleotidyl transferase/hydrolase domain of the type found in the type IA family of DNA topoisomerases (TopoIA). This subgroup contains proteins similar to the Type I DNA topoisomerases: E. coli topisomerases I and III, eukaryotic topoisomerase III and, ATP-dependent reverse gyrase found in archaea and thermophilic bacteria. Type IA DNA topoisomerases remove (relax) negative supercoils in the DNA. These enzymes cleave one strand of the DNA duplex, covalently link to the 5' phosphoryl end of the DNA break and allow the other strand of the duplex to pass through the gap. Reverse gyrase is also able to insert positive supercoils in the presence of ATP and negative supercoils in the presence of AMPPNP. The TOPRIM domain has two conserved motifs, one of which centers at a conserved glutamate and the other one at two conserved aspartates (DxD). For topoisomerases the conserved glutamate is believed to act as a general b
