STRUCTURE OF COLICIN E7 IMMUNITY PROTEINSTRUCTURE OF COLICIN E7 IMMUNITY PROTEIN
Structural highlights
FunctionIMM7_ECOLX This protein is able to protect a cell, which harbors the plasmid ColE7 encoding colicin E7, against colicin E7, it binds specifically to the DNase-type colicin and inhibits its bactericidal activity. Dimeric ImmE7 may possess a RNase activity that cleaves its own mRNA at a specific site and thus autoregulates translational expression of the downstream ceiE7 gene as well as degradation of the upstream ceaE7 mRNA. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. See Also |
