CcdB is the toxic component of a bacterial toxin–antitoxin system. It inhibits DNA gyrase (a type II topoisomerase), and its toxicity can be neutralized by binding of its antitoxin CcdA. Here we report the sequential backbone and sidechain 1H, 15N and 13C resonance assignments of CcdBVfi from the marine bacterium Vibrio fischeri. The BMRB accession number is 16135.
