Comparison of the Y. pestis Ypf prophage and the PhiYep-1 prophage in Y. enterocolitica O:3/4. The Ypf prophage is representing a typical structure of a filamentous phage, with genes for morphogenesis, secretion and replication. The cluster in O:3/4 is notably reduced, and in strain Y5307 the Yep prophage is reduced to only three truncated genes left, as proven by sequencing.
