The Distribution, Evolution, and Roles of Gene Transfer Agents in Prokaryotic Genetic Exchange.
Diverse prokaryotes produce gene transfer agents (GTAs), which are bacteriophage-like particles that exclusively package pieces of the producing cell's genome and transfer them to other cells. ThereExpand

One for All or All for One: Heterogeneous Expression and Host Cell Lysis Are Key to Gene Transfer Agent Activity in Rhodobacter capsulatus
The gene transfer agent (RcGTA) of Rhodobacter capsulatus is the model for a family of novel bacteriophage-related genetic elements that carry out lateral transfer of essentially random host DNA.Expand

Phosphate concentration and the putative sensor kinase protein CckA modulate cell lysis and release of the Rhodobacter capsulatus gene transfer agent.
The gene transfer agent of Rhodobacter capsulatus (RcGTA) is a bacteriophage-like genetic element with the sole known function of horizontal gene transfer. Homologues of RcGTA genes are present inExpand

Guaranteeing a captive audience: coordinated regulation of gene transfer agent (GTA) production and recipient capability by cellular regulators.
Gene transfer agents (GTAs) are bacteriophage-like particles produced by many prokaryotes. Several members of the Alphaproteobacteria produce a class of genetically-related GTAs that is best studiedExpand

The SOS Response Master Regulator LexA Regulates the Gene Transfer Agent of Rhodobacter capsulatus and Represses Transcription of the Signal Transduction Protein CckA.
UNLABELLED The gene transfer agent of Rhodobacter capsulatus (RcGTA) is a genetic exchange element that combines central aspects of bacteriophage-mediated transduction and natural transformation.Expand

The Gene Transfer Agent RcGTA Contains Head Spikes Needed for Binding to the Rhodobacter capsulatus Polysaccharide Cell Capsule.
Viruses and bacteriophages recognize cell surface proteins using receptor-binding proteins. In most tailed bacteriophages, receptor-binding proteins are located on the bacteriophage tail. The geneExpand

The Protease ClpXP and the PAS Domain Protein DivL Regulate CtrA and Gene Transfer Agent Production in Rhodobacter capsulatus
ABSTRACT Several members of the Rhodobacterales (Alphaproteobacteria) produce a conserved horizontal gene transfer vector, called the gene transfer agent (GTA), that appears to have evolved from aExpand

Gene co-expression network analysis in Rhodobacter capsulatus and application to comparative expression analysis of Rhodobacter sphaeroides
BackgroundThe genus Rhodobacter contains purple nonsulfur bacteria found mostly in freshwater environments. Representative strains of two Rhodobacter species, R. capsulatus and R. sphaeroides, haveExpand

The Rhodobacter capsulatus gene transfer agent is induced by nutrient depletion and the RNAP omega subunit.
Small bacteriophage-like particles called gene transfer agents (GTAs) that mediate DNA transfer between cells are produced by a variety of prokaryotes. The model GTA, produced by theExpand
