Structural Insight into How Bacteria Prevent Interference between Multiple Divergent Type IV Secretion Systems
UNLABELLED Prokaryotes use type IV secretion systems (T4SSs) to translocate substrates (e.g., nucleoprotein, DNA, and protein) and/or elaborate surface structures (i.e., pili or adhesins). Bacterial genomes may encode multiple T4SSs, e.g., there are three functionally divergent T4SSs in some Bartonella species (vir, vbh, and trw). In a unique case, most rickettsial species encode a T4SS (rvh) e...
متن کاملType VI secretion systems in plant‐associated bacteria
The type VI secretion system (T6SS) is a bacterial nanomachine used to inject effectors into prokaryotic or eukaryotic cells and is thus involved in both host manipulation and interbacterial competition. The T6SS is widespread among Gram-negative bacteria, mostly within the Proteobacterium Phylum. This secretion system is commonly found in commensal and pathogenic plant-associated bacteria. Phy...
متن کاملNamed Entity Recognition for Bacterial Type IV Secretion Systems
Research on specialized biological systems is often hampered by a lack of consistent terminology, especially across species. In bacterial Type IV secretion systems genes within one set of orthologs may have over a dozen different names. Classifying research publications based on biological processes, cellular components, molecular functions, and microorganism species should improve the precisio...
متن کاملFunctional divergence and horizontal transfer of type IV secretion systems.
The type IV secretion system (TFSSs) is a multifunctional family of translocation pathways that mediate the transfer of DNA among bacteria and deliver DNA and proteins to eukaryotic cells during bacterial infections. Horizontal transmission has dominated the evolution of the TFSS, as demonstrated here by a lack of congruence between the tree topology inferred from components of the TFSS and the...
متن کاملEvolution of Conjugation and Type IV Secretion Systems
Genetic exchange by conjugation is responsible for the spread of resistance, virulence, and social traits among prokaryotes. Recent works unraveled the functioning of the underlying type IV secretion systems (T4SS) and its distribution and recruitment for other biological processes (exaptation), notably pathogenesis. We analyzed the phylogeny of key conjugation proteins to infer the evolutionar...
