NMR Structure(hide GO term definitions)
Chain A   (IMM8_ECOLX | P09881)
molecular function
    GO:0015643    toxic substance binding    Interacting selectively and non-covalently with a toxic substance, a poisonous substance that causes damage to biological systems.
biological process
    GO:0030153    bacteriocin immunity    A process that mediates resistance to a bacteriocin: any of a heterogeneous group of polypeptide antibiotics that are secreted by certain bacterial strains and are able to kill cells of other susceptible (frequently related) strains after adsorption at specific receptors on the cell surface. They include the colicins, and their mechanisms of action vary.
