Dates 14-JAN-2013 (Created)
27-OCT-2018 (Last updated, Version 16)
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=5.99.1.3;

Comments [?]

Catalytic activity Reaction=ATP-dependent breakage, passage and rejoining of double- stranded DNA.; EC=5.99.1.3;.
Cofactor Mg(2+)
Mn(2+)
Ca(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.

Keywords [?]

DNA-binding
end case

case <FTGroup:1>
