Enzyme Information

3.1.22.4

Crossover junction endodeoxyribonuclease.

based on mapping to UniProt P0A814

Endonucleolytic cleavage at a junction such as a reciprocal single- stranded crossover between two homologous DNA duplexes (Holliday junction).

-!- The enzyme from Saccharomyces cerevisiae has no endonuclease or exonuclease activity on single-stranded or double-stranded DNA molecules that do not contain Holliday junctions.
