[Перевод] О прионах и дизайне белков
Зачастую крупные открытия в области биологии происходят при изучении крошечных существ. И многое из того, что мы сегодня считаем догмой, появилось благодаря изучению конкретных микроорганизмов. Эксперименты с бактерией Streptococcus pneumoniae не только привели к открытию ДНК как основной наследственной молекулы , но и позволили создать первые инструменты для генной инженерии. Изучение РНК опухолевых вирусов позволило обнаружить обратную транскриптазу — фермент, необходимый для изучения биологии РНК. Эти модельные микроорганизмы долгое время служили природными лабораториями, позволяя расшифровывать фундаментальные принципы жизни и предоставляя инструменты, необходимые для их изучения. Перейдя от микроорганизмов к макромолекулам, биология вступила в эру белков. Последние достижения в области искусственного интеллекта, включая такие инструменты, как нобелевский лауреат AlphaFold , сделали возможным предсказание структуры белков, превратив кропотливый лабораторный процесс в вычислительную задачу, которую можно решить за считанные минуты.

Nice study from @teresa_omeara & @maom in @biorxivpreprint
They used protein prediction to explore the poorly annotated Candida auris genome, and then used protein design to replace endogenous proteins with de novo designed ones.
A central tenet of biology is that protein structure mediates the sequence-function relationship. Recently, there has been excitement about the promise of advances in protein structure modeling to generate hypotheses about sequence-structure-function relationships based on successes with controlled benchmarks. Here, we leverage structural similarity to identify rapidly evolving proteasome assembly chaperones and characterize their function in the emerging fungal pathogen Candida auris. Despite the large sequence divergence, we demonstrate conservation of structure and function across hundreds of millions of years of evolution, representing a case of rapid neutral evolution. Using the functional constraints on structure from these naturally evolved sequences, we prospectively designed de novo chaperones and demonstrate that these artificial proteins can rescue complex biological processes in the context of the whole cell. ### Competing Interest Statement The authors have declared no competing interest.
