An error-prone process for repairing damaged microbial DNA.

A DNA repair process that involves the exchange, reciprocal or nonreciprocal, of genetic material between the broken DNA molecule and a homologous region of DNA.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electromagnetic radiation stimulus. Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.

An error-prone process for repairing damaged microbial DNA.

The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.

Any process in which a new genotype is formed by reassortment of genes resulting in gene combinations different from those that were present in the parents. In eukaryotes genetic recombination can occur by chromosome assortment, intrachromosomal recombination, or nonreciprocal interchromosomal recombination. Interchromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction.

A DNA helicase complex found at Holliday junctions where the helicase activity is involved in the migration of the junction branch point. The best-characterized example is the E. coli RuvAB complex, in which a hexamer of RuvB subunits possesses helicase activity that is modulated by association with RuvA.

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.
