WebDec 1, 2002 · The term Integrative Conjugative Elements (ICE) was first proposed by Burrus et al. to describe bacterial mobile genetic elements (MGEs) that are self-transmissible, integrate into and excise... Although ICEs exhibit various mechanisms promoting their integration, transfer and regulation, they share many common characteristics. ICEs comprise all mobile genetic elements with self-replication, integration, and conjugation abilities, including conjugative transposons, regardless of the particular conjugation and integration mechanism by which they act. Some immobile genomic pathogenicity islands are also believed to be defective ICEs that have lost their ability to conjugate.
