Bacteriophages are the predominant biological entity on Earth. However, despite being among the earliest and best characterised phage family, and forming the basis of many tools in molecular biology, we only recently began to understand the global diversity and biological impact that the filamentous phage (family Inoviridae) have on our biosphere. The filamentous phage are unique in that they can establish a chronic infection, where the phage progeny exit a host cell via a purpose-built phage assembly and secretion system present in the bacterial cell envelope; meaning the host cell is not typically lysed. The diversity, architecture, and interaction of this trans-envelope nanomachine is largely uncharacterised. Here, we explore the diversity of the filamentous phage assembly/secretion systems. We show preliminary assessment of the architecture of a model system and probe how components of the system interact.
