Bacteria use the type IV secretion systems (T4SS) to transport virulence factors into eukaryotic cells (such as Legionella pneumophila), passing on genetic material between bacteria, including the transmission of antibiotic resistance genes between different bacteria , To promote the spread of resistant bacteria. T4SS may also serve as a potential tool for genetic modification of human cells.
A study published in Nature in March 2014 revealed the structure and mechanism of bacterial type IV secretion. Researchers used electron microscopy to reconstitute a type IV secretion system encoded by the conjugate plasmid of E. coli R388. The results showed that bacterial T4SS, whether it is molecular structure or secretion mechanism, has the essential difference from other bacterial secretion systems. The bacterial type IV secretion system is a complex structure assembled from eight proteins that are about 3 Da in size throughout the bacterial membrane. T4SS consists of two separate complexes, one on the bacterial outer membrane and the other on the bacterial inner membrane. They connect through the periplasm through a stemlike structure. The periplasm is located in the space between the bacterial endometrium and the outer membrane. As a result, a cell-like structure is formed in the cell membrane by which bacteria release the substance.
Clarifying the structure of the bacterial type IV secretion system can help people design new drugs to target this system shut down and thus prevent the spread of antibiotic resistance genes among bacteria. Given the current prevalence of bacterial resistance has become so widespread that it is a serious threat to human health, the results of this study will have a huge impact on the future of bacterial resistance research. Giant DNA bacterial toxins are visible under light microscopy, and their genome encodes more proteins than some bacteria or intracellular parasitic eukaryotes. Two distinct bacterial strains of bacteria have now been discovered, all of which are capable of infecting unicellular protists, such as Acanthamoeba. On the one hand, Megaviridae has a large pseudoicosahedral capsid which encloses genomes of adenine and thymine rich in megapores; on the other hand, the recently discovered Pandora bacteria toxin Pandoraviruses) have micron-sized binocular cans and bacteria up to 2.8 MB of guanine and cytosine-rich genomes.
