We have applied for funding. The leaderless bacteriocin enterocin K1 is highly potent against Enterococcus faecium: A study on structure, target spectrum and receptor. A hydrophobic patch in the competence-stimulating peptide, a pneumococcal competence pheromone, is essential for specificity and biological activity. The interactions between the two peptides will be the scope of further investigation. Measurements of the effect on anti-microbial activity of single glycine replacements in PlnJ and PlnK show that Gly-13 and Gly-17 in both peptides are very sensitive, giving more than a 100-fold reduction in activity when large residues replace glycine. Website ping to the server is timed at 473 ms. Some peptide bacteriocins referred to as two-peptide bacteriocins , such as lactococcin G, consist of two different peptides and both peptides must be present in order for the bacteriocin to kill the target bacteria.

Three-dimensional structure of the two peptides that constitute the two-peptide bacteriocin lactococcin G. Strengthen the expertise in both three-dimensional structure- and function- analysis of biological macromolecules by performing a variety of experiments and employing different structure determination tools and also by educating Ph. It is proposed that the detrimental effect on activity when exchanging Gly-13 and Gly-17 in PlnJ and PlnK is a result of reduced ability of the two peptides to interact through the GxxxG-motifs constituting Gly-13 and Gly-17. The hinge between the two helices may introduce the flexibility that allows the helix to dip into membranes. Selective membrane disruption by the cyclotide kalata B7: complex ions and essential functional groups in the phosphatidylethanolamine binding pocket.

Lactococcin G contains three such GxxxG-motifs, two in the α-peptide G7xxxG11 and G18xxxG22 and one in the β-peptide G18xxxG22. The helix-hinge-helix motif is made up of a short polar helix and a longer C-terminal hydrophobic helix separated by a hinge region. Accordingly, immunotherapeutic approaches might have the potential to improve outcome in patients with vulvar cancer and could complement conventional cancer treatment. The 32 residues long PlnK forms a central amphiphilic α-helix between Gly-9 and Leu-24. PlnJ, a 25 residue peptide, has an N-terminal amphiphilic α-helix between Trp-3 and Tyr-15. The peptides are unstructured in water but becomes structured when in contact with membranes Hauge et al. All two-peptide bacteriocins contain GxxxG-motifs which are known to mediate helix-helix interactions in membrane proteins.

The results indicate that the G7xxxG11-motif in the α-peptide and G18xxxG22-motif in the β-peptide are important in helix-helix interactions between the two lactococcin G peptides and that the two peptides form a transmembrane helix-helix structure.
