Uniprot: A9NGG7
Description: Holliday junction resolvase RecU
EC number: 3.1.22.-
Annotation score: 3 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity:
Cofactor: COFACTOR: Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP-Rule:MF_00130}; ; Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00130}
Enzyme regulation:
Function [CC]: FUNCTION: Endonuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves mobile four-strand junctions by introducing symmetrical nicks in paired strands. Promotes annealing of linear ssDNA with homologous dsDNA. Required for DNA repair, homologous recombination and chromosome segregation. {ECO:0000256|HAMAP-Rule:MF_00130, ECO:0000256|SAAS:SAAS00368725}.
