Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (GAM_LAMBD | P03702)
molecular function
    GO:0060703    deoxyribonuclease inhibitor activity    Stops, prevents or reduces the activity of deoxyribonuclease.
biological process
    GO:0032076    negative regulation of deoxyribonuclease activity    Any process that stops or reduces the rate of deoxyribonuclease activity, the hydrolysis of ester linkages within deoxyribonucleic acid.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
