General rule information [?]

Accession PRU00995
Dates 14-JAN-2013 (Created)
21-NOV-2019 (Last updated, Version 20)
Data class Domain
Predictors PROSITE; PS50880; TOPRIM
Name Toprim domain
Function The Toprim domain is a catalytic domain involved in DNA strand breakage and rejoining.

Propagated annotation [?]

Description [?]

case <FTGroup:1> and <FTGroup:2>
+ RecName: EC;

Comments [?]

Catalytic activity Reaction=ATP-dependent breakage, passage and rejoining of double-stranded DNA.; EC=;
Cofactor Mg(2+)
Note: Binds two Mg(2+) per subunit. The magnesium ions form salt bridges with both the protein and the DNA. Can also accept other divalent metal cations, such as Mn(2+) or Ca(2+).
else case <FTGroup:1>
Cofactor Mg(2+)
Note: Binds two Mg(2+) per subunit.
end case

Gene Ontology [?]

case <FTGroup:1>
GO:0000287; Molecular function: magnesium ion binding.
end case

case <FTGroup:2>
GO:0003677; Molecular function: DNA binding.
