Role of the Small Terminase Subunit Encoded by Staphylococcus Aureus Pathogenicity Island SaPI1 in Formation of SaPI1 Transducing Particles
Staphylococcus aureus pathogenicity island SaPI1 is a genomic element that is mobilized and transduced at high frequency by helper phage 80α. SaPI1 encodes a small terminase protein that belongs to the phage small terminase subunit family. The presence of SaPI1-encoded small terminase suggests that …

Helper phage capsid size redirection by staphylococcal pathogenicity island SaPI1 involves internal scaffolding proteins.
… Two proteins encoded by the prototype element SaPI1, gp6 and gp7, have been identified in SaPI1 procapsids but not in mature SaPI1 particles. These proteins are sufficient and required to direct small capsid formation, which involves alteration of an internal scaffold. While many phages use …

Identification and Characterization of Helper Phage Gene Products Involved in Mobilization of Staphylococcal Pathogenicity Island SaPI1
Staphylococcal pathogenicity island SaPI1 is excised from genomic DNA and extrachromosomal copies are amplified during the vegetative growth of staphylococcal phage 80α. The amplified genetic element is subsequently encapsidated and transduced at very high frequency. Previous studies have …
