Insecticidal toxin gene complex in Y. enterocolitica O:9/2, O:3/4 and O:5,27/3. The structural organisation of the cluster is the same in all serobiotypes, but the encoded proteins differ in length and are to some extent fragmented. For O:5,27/3, the cluster is the only one with only a single tcaC gene. In addition, the tcaR2 is, as well as tcaB, complete.
