Non-cognate protein-protein interactions: the NMR structure of the colicin E8 inhibitor protein Im8 and its interaction with the DNase domain of colicin E9
1gxg is a 1 chain structure with sequence from Escherichia coli. This structure supersedes the now removed PDB entry 1imz. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
IMM8_ECOLX This protein is able to protect a cell, which harbors the plasmid ColE8 encoding colicin E8, against colicin E8, it binds specifically to the DNase-type colicin and inhibits its bactericidal activity.
