Interpretive Summary:

Technical Abstract: The predicted gene product of the P. syringae gene is similar to the yedK gene of Escherichia coli (accession:NP 288392) and the 'Gyfsy-2' prophage in Salmonella typhimiurium (accession: NP 460027). The gene also contains significant identity to similar gene in Pseudomonas syringae pv. pisi (accession:CAB96973). Members of this gene family are found widely distributed across taxa of all three Domains. The presence of the a phage associated gene next to the tabtoxin biosynthetic cluster, strongly suggest a mechanism for the horizontal transfer and integration of the tabtoxin pathogenicity island. This mechanism entails the transfer of the region via wide-host range plasmids or bacterial conjugation followed by the integration of the entire tabtoxin biosynthetic cluster as a unit using a phage-like integrase.
