Additionally, s pyocin gene clusters lack a lysis gene, indicating that different mechanisms might be involved in their release. Although much less documented, the import pathway of pyocins is probably similar to that for colicin uptake.

A central question in microbial ecology is whether microbial interactions are predominantly cooperative or competitive. The secretion of siderophores, microbial iron chelators, is a model system for cooperative interactions. However, siderophores have also been shown to mediate competition by sequestering available iron and making it unavailable to competitors.

We repeated the evolution experiment as described above in non-toxic but iron-limited conditions (kb + 100 μg ml −1 human apotransferrin and 20 mm nahco 3) and in standard kb media (nutrient-rich control), aliquoting 1% (approx. 10 6 cfus) of each culture to new medium every 24 h for a total of 33 transfers (approx.
We also report cases where duplications of receptor genes are observed and the presence of ‘receptor islands’. Our study strongly supports the notion of ‘core’ and ‘accessory’ tonb‐dependent receptors within each species, with the ferripyoverdine receptors belonging to the last category.

Pyoverdines are a group of structurally related siderophores produced by fluorescent pseudomonas species. Recent genomic and biochemical data have shed new light on the complex molecular steps of pyoverdine biogenesis and explained the chemical diversity of these compounds. In the opportunistic pathogen pseudomonas aeruginosa, pyoverdine is necessary for infection in several different disease.

The cognate ferripyoverdine receptor, fpva, has gained attention as the most divergent gene in the organism’s genome, showing substantial evidence of positive selection. S-type pyocins, bacteriocins with specificity to pseudomonads, enter cells through fpva and therefore may play a role in the evolution of these receptors.

Evolution of ferripyoverdine receptors in pseudomonas aeruginosa is a scientific work written by julie osaretin osayande, a molecular biologist. Pseudomonas aeruginosa is a type of bacteria that occurs in nature as well as in hospitals, where it attacks patients who have compromised immune systems.
However, the use of a ferripyoverdine receptor by s1, s2 and s3 pyocins, allows us to suppose that the mechanism of translocation is similar to that of this ferrisiderophore, via the tonb system 〚59〛. For ap41 pyocin, the tolqra (or pig6) system could be involved.
