Prions are misfolded proteins that acts as catalysts for other proteins to fold in new, pathological state. They are built of normal L-amino acids.
"Mirror-image peptides" are built of amino-acids with reverse chirality: https://en.wikipedia.org/wiki/Chirality https://en.wikipedia.org/wiki/Chirality
They have almost nothing common, except for being made of amino-acids.
- ohazi 5y agoI once heard someone suggest that creating mirror-prions out of mirror-proteins might one day be a safer way to study prion diseases, since an accidental leak wouldn't be able to trigger the misfolding cascade on the researcher's own proteins, since they're not mirrored. No idea if this was meant seriously, but it simultaneously sounds reasonable and terrifying...
- Ginden 5y agoThat's something that have to be tested - I would expect that mirror prions would misfold normal proteins too, but it's dependent on details of chemical process. Prions are scary.
