Cytolethal distending toxin (CDT) induces cell cycle arrest and apoptosis in eukaryotic cells, which are mediated by the DNA-damaging CdtB subunit. Here we report the first x-ray structure of an isolated CdtB subunit (Escherichia coli-II CdtB, EcCdtB). In conjunction with previous structural and biochemical observations, active site structural comparisons between free and holotoxin-assembled CdtBs suggested that CDT intoxication is contingent upon holotoxin disassembly ...
