Peptides consist of 2 amino acids linked together by their amino and carboxyl groups; eliminating a water molecule in the process and forming a peptide bond. Informally, they are tiny proteins, however, a protein would technically need many more amino acids. By definition, any amino acid chain longer than 50 would constitute as a protein.

New publication out!

We were curious what happens with the lipid membrane if proteins are inside. As a model of membrane proteins we use transmembrane peptides with neutral and positive charge. The charges turn out to be quite crucial in the peptides influence on the lipids.

publication link: https://doi.org/10.1016/j.colsurfb.2024.113765…

All transmembrane peptides hinder mobility of lipids around. The positive charges in the peptide make this hindering a long range influence.

The membrane with the positive peptides then has heterogeneities in the lipid mobility. This hampers free rearrangement of lipids and leads to lower ability to seal ruptures. You can see below how the membrane stays fragmented after indentations with AFM (atomic force microscope), which is basically a very tiny tip that scans the surface of the membrane for images and can also push through it to test mechanical stability.

For comparison this is how it looks like with a membrane without any peptides. The mebrane seals the ruptures induced by the AFM tip and recovers its round shape. The same happens if we have a neutral, non-charged, peptide.

With this work we highlight the importance of including charges of proteins and peptides in membrane model studies.

And last but not least...

This is the very first time I am the last corresponding author of a publication. I am immensely proud on myself!

Lasso peptides are a really cool family of peptides that have a very unique knotted structure and are chronically understudied and poorly understood. Lasso peptides get their name from the way the N-terminus wraps back around the peptide chain and forms an isopeptide bond with the carbonyl of a Glu/Asp residue, forming a literal lasso like shape:

This is a deceptively tricky reaction to study, let alone replicate. At the minute, most studies done on identifying and isolating these molecules use overexpression, chemical or even biosynthetic strategies are inaccessible, which is a real shame because the unusual topologies of these peptides gives them excellent protease resistance and much better pharmacokinetics than linear, or even standard cyclic peptides.

More detailed images of the peptides reveal some interesting quirks of how they adopt this unique shape:

This stick model on the left show the whole lasso peptide, with the section forming the ring highlighted in green. The sequence that is ‘lasso’d’ so to speak is quite interesting, and is shown on the right. The C terminal tryptophan-phenylalanine motif is common among lasso peptides and acts as a ‘stopper’ and provides a, frankly massive, steric barrier to unfolding the lasso. The encapsulated section is comprised of glycine which is pretty easy to rationalise because glycine doesn’t have a side chain, thus making it the most suitable for threading through a ring. I’ve also highlighted the proline, which is also common among lasso peptides, it is though that the proline is important to preorganising the lasso before the ring is completed, proline is a much more restricted amino acid than the others and often adopts this role as a conformational guide.

Its worth remembering just how tight this whole arrangement is, threading a peptide though a 7 residue ring is no small feat, and here’s the space filling model to highlight that fact:

There is no wiggle room at all, and that is key to understanding why these things are so hard to make, they incur a huge entropic and steric penalties for being in these tightly wound conformations and aren’t offsetting that by forming covalent bonds or massive protein scale stabilising interactions. As such I think they’re pretty remarkable and definitely worth studying more.
