Contact-dependent growth inhibition (CDI) is a mechanism of inter-cellular competition in which Gram-negative bacteria exchange polymorphic toxins using type V secretion systems. Structure analysis of the CDI toxin from Escherichia coli NC101 reveals that it has moderate structural homology to Whirly-like proteins found in plastids, but appears to lack the characteristic Whirly RNA-binding site [1].
