Eternity Life Clinics - Scientists are using AI to create new proteins

Tremendous developments in the field of computer science open up multiple possibilities and due to it biologists can dream up 100% natural molecules in the nick of time instead of long weeks or even months. Recently, South Korea approved a COVID19 vaccine, constituted from new proteins developed by people. The medication is grounded on a spherical protein ‘nano-particle’ produced through a labor-intensive trial-and-error process.

AI defines the shape of almost all known proteins

AI instruments such as DeepMind’s software ΑlphaFold which can predict protein structures are actively applied for research purposes. In the past, this had been a challenging task with high likelihood of failures. Biologists and a plethora of organizations that are using AI for enzyme designing aim to create substances that can have a beneficial impact on human organisms, from getting rid of dangerous pathogens to curing illnesses. Among the organizations that are pursuing this purpose are Deep-Mind and Meta.

Designing proteins from scratch

A try to dream up the first enzymes dates back to the 1990s, when software under the name of Rοsetta was applied to research by Baker’s laboratory. The first proteins designed by AI in the majority of cases did not set up into the expected shape when produced in the laboratory. That’s why a new step was necessary to set the enzyme sequencing in such a way that it set up only into an expected form.

With ΑlphaFold and other AI programs, that slow process has become very fast. These tools were instructed to forecast the structural aspect of separate set of amino acids. But biologists saw that such software had also an ability to create sets of a range of enzymes that form functional interactions. At this point, they assured they were able to dream up enzymes that would assemble themselves into nano-particles of various forms and parameters. Such proteins would consist of a bunch of duplicates of one enzyme and resemble those on which the COVID19 medicine is grounded.

 Deep-learning revolution

Baker’s laboratory isn’t the only organization using AI to create protein artificially. According to biοRxiv, there are more than forty AI programs that have been available recently that apply different methods.

The majority of these programs deal with the inverse fοlding algorithm issue: they determine sequencing type that is right to a certain composition, often applying methods used in picture-recognition software. Others are grounded on architectures close to that of natural language processing systems, which produce texts; however, in lieu of texts, the programs define protein sequencing.

Follow-up studies

Scientists at Baker’s lab are sure that designing proteins in the laboratory conditions is the conclusive analysis of their approaches. But not all biologists working on AI software for enzyme designing have hassle-free access to exploratory setups, and this is challenging for testing their findings, as finding a lab to make probing can be time-consuming.

Research will also be of high significance concerning dreaming up proteins for certain tasks. For this purpose, Baker’s lab shared several AI arrangements that make it possible for scientists to imbed a certain sequencing order in a new enzyme. These methods were useful in designing enzymes that catalyze certain responses:

  • proteins able of joining other particles; and
  • proteins that potentially can be applied in medicines against respiratοry viruses.

We are in social networks

  • The goal that we have set for ourselves is the acquisition by the human body of the ability to remain young and healthy as long as possible – practically, the acquisition of immortality by a person.

    A young man at 100 years of age? Why not? And this is just the tip of the iceberg of our plans.

  • The main and most global goal of the project is to gain immortality. However, to achieve this goal, there is a lot of work to be done: from introducing the latest developments in medical practice, which already now can significantly improve health and prolong life, to conducting scientific research that will help achieve our global goal.

  • A fund or a company interested in investing in our project can contact us via the contact form to clarify all the details. The main condition is the sharing of project values ​​and the desire to change the world for the better together with us.

    In addition, we plan to issue our own NFT collection, by purchasing which you will also be able to invest in the project.

  • Since we create the ELC project from scratch and fully cover all our activities in social networks, you can learn about all promotions and developments from our official pages and website. One of the first public results will be the presentation of the project at the Eternity Life Forum, where we will present our project, with its ideas and developments.
