“Background The α-proteobacterium Rhodobacter capsulatus is one of several known species of prokaryotes that produces a gene transfer agent [1], or GTA. GTAs are phage-like particles that contain small fragments of the producing cells’ genomes [2] that can then be transferred to other cells in a process similar to generalized transduction. Production of the R. capsulatus GTA, RcGTA, is regulated through multiple E7080 cellular signal transduction systems. These include the GtaRI quorum sensing system [3, 4] and the phosphorelay proteins CtrA and CckA [5, 6] and ChpT [6].
