Transducing particles of Staphylococcus aureus pathogenicity island SaPI1 are comprised of helper phage-encoded proteins.

Journal of Bacteriology 189(20):7520 (2007) PMID 17693489 PMCID 2168463

The relationship between the composition of SaPI1 transducing particles and those of helper phage 80alpha was investigated by direct comparison of virion proteins. Twelve virion proteins were identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and mass spectrometry; all were present in both 80alpha and SaPI1 virions, and all were encoded by 80alpha. No SaPI1-encoded proteins were detected. This confirms the prediction that SaPI1 is encapsidated in a virion assembled from helper phage-encoded proteins.
