Asymmetric Unit(hide GO term definitions)
Chain A,B   (RECR_BPP1 | P06956)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
biological process
    GO:0015074    DNA integration    The process in which a segment of DNA is incorporated into another, usually larger, DNA molecule such as a chromosome.
    GO:0006310    DNA recombination    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. Intrachromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction.
