ICE family: Tn5253
Tn5253 is a composite structure of two conjugative transposons, Tn5251 and Tn5252. We selected it as a reference and defined Tn5253 family. We classified ICE that has significant sequence alignment and syntenic 'core' structure with Tn5253 into the Tn5253 family, including Tn5252 and Tn5252-like ICEs.
