four-way junction helicase activity

Unwinding a DNA helix of DNA containing four-way junctions, including Holliday junctions, driven by ATP hydrolysis.

meiotic strand invasion involved in reciprocal meiotic recombination

The cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate resulting in meiotic recombination. Meiotic recombination is the cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate.

replication fork reversal

Replication fork processing that involves the unwinding of blocked forks to form four-stranded structures resembling Holliday junctions, which are subsequently resolved.

meiotic strand invasion involved in meiotic gene conversion

The cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate resulting in meiotic recombination.

crossover junction DNA endonuclease activity

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

resolution of meiotic recombination intermediates

The cleavage and rejoining of intermediates, such as Holliday junctions, formed during meiotic recombination to produce two intact molecules in which genetic material has been exchanged.

resolution of DNA recombination intermediates

The cleavage and rejoining of intermediates, such as Holliday junctions, formed during DNA recombination to produce two intact molecules in which genetic material has been exchanged.

Holliday junction resolvase complex

An endodeoxyribonuclease complex that resolves the 4-way DNA intermediates of a Holliday junction into two separate duplex DNA molecules. Can be branch-migration associated.

activation of reciprocal meiotic recombination

Any process that starts the inactive process of reciprocal meiotic recombination. Reciprocal meiotic recombination is the cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate.

negative regulation of reciprocal meiotic recombination

Any process that decreases the frequency, rate or extent of recombination during meiosis. Reciprocal meiotic recombination is the cell cycle process in which double strand breaks are formed and repaired through a double Holliday junction intermediate.
