Asymmetric Unit(hide GO term definitions)
Chain A,B   (TNSA_ECOLX | P13988)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0004518    nuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids.
    GO:0003676    nucleic acid binding    Interacting selectively and non-covalently with any nucleic acid.
    GO:0004803    transposase activity    Catalysis of the transposition of transposable elements or transposons. Transposases are involved in recombination required for transposition and are site-specific for the transposon/transposable element.
biological process
    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.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
    GO:0032196    transposition    Any process involved in mediating the movement of discrete segments of DNA between nonhomologous sites.
    GO:0006313    transposition, DNA-mediated    Any process involved in a type of transpositional recombination which occurs via a DNA intermediate.
cellular component
    GO:0000229    cytoplasmic chromosome    A chromosome found in the cytoplasm.
