      @@cyberneticbutterfly8506 The issue with all of this is - as was the case with crystal structures - that they show just what the name says; the situation in the crystal. Proteins are not a static thing. To perform their function they have to change in shape (extreme example DNA Pol opens and closes in a 40° angle between domains). So the next step is goin from crystal to solution. I'm not an expert on the computational side of things but I'd guess we're quite far off on that. Don't get me wrong, this is amazing and incredibly useful, but the next step is just as hard.

    My dad is a molecular biologist and runs a biochem company that specializes in enzyme technologies. His work revolves around creating proteins(enzymes) that are high performant and can massively increase production efficiency for drugs/ingredients and etc. This means a huge amount of laborious lab testing the performance of many proteins they created from the ground up. Computational prediction of protein structures was a frequent topic of our casual discussions, with him often being pessimistic about it, saying that proteins are the most complex structures in the universe, and the combinations are infinitely endless, and that only a quantum computer can begin to qualify such a task. Because I work in I.T, I tend to console him with the notion that A.I algorithms these days are surprisingly powerful, and maybe more suitable for such endeavors. We've had this type of dialogue for years. A few days ago when I sent him the news of this breakthrough he was in complete shock. He said this will change the whole game for the entire drugs and biotechnology industry.

    I am a Canadian Masters Student in Computer Science and with a Bachelor Honors in Biochemistry. I actually just wrote a research proposal for a grant that was about the functional prediction from protein structure. So I have recently read up on this literature a bit. Not saying I am an expert though! I think the biggest implications are for protein engineering. Since proteins (Enzymes to be specific) are responsible for the metabolites of all living organisms, being able to design enzymes to produce natural products efficiently is incredible for the production of drugs and almost any other material tbh. Currently, there is literature on how to predict optimal binding sites, but turning that into a functional enzyme is tough. This takes lots of expensive iterations. This is because our prediction models are bad and predicting if proteins are stable to fold. Because models are trained on natural proteins that function the programs aren't great at telling us what is stable or not, just what a possible fold maybe. but with advancements like these, we will likely get closer to predicting the stability and function of proposed sequences making engineering a possibility.
    Another huge implication is the possible discovery of uncultivatable proteins. A significant amount of biomass on earth cannot be grown in a lab. This leaves an ungodly amount of organisms and their components unstudied. But, the field of metagenomics takes DNA and RNA samples found from soil or other samples and reconstructs potential genomes. From genomes, we can predict possible amino acid sequences and from that, we can predict natural proteins that we would have never seen before!!! There is always a risk that since the data is from organisms that are cultivatable that the proteins of others may be different in some way, but that is extremely unlikely to be an issue in my opinion. Very Exciting!! On top of this, if we can predict ligand/substrate binding then we can see natural biological compounds that we haven't seen in the lab before! Natural products have a high efficacy in drug discovery so this is fantastic!
    Big things that still need to be done, in the field are stability prediction, function prediction, ligand/substrate binding prediction, product prediction, dynamic movement prediction for enzymes that go through conformational changes. Lots ahead, but breakthroughs like this make me super hopeful!
    You're an inspiration Lex! I am hoping to make an impact on substrate/product prediction myself with applications of deep learning!

    Mind was blown when I first read this. I think a lot of people don't quite understand just how amazing this is (or at least will be in the near future). I'm not in drug design etc for now, but I work in medicine. This is completely world-changing for so many entities out there depending on crystallography or just trial and error.

If your work is mentioned in three Nobel fields, I can’t even find words for how amazing what you’re doing is. This will change our lives forever even if we don’t notice.

    Just one thing about misfolding. Misfolding are of not too big interest to most molecular biologists. It does play a role in some diseases, but most of diseases are caused by other things. Biologists just want to know the structure to know how it interacts with other molecular machinery, be it healthy or unhealthy parts, or in pathogens. The 3D structure is just useful for many things, be it progressing knowledge, drug design, etc. Also a lot of proteins are composed of more than just amino acids. They can have so called post-translation modifications (happens after translation or during), that do include extra attached groups, be it non-amino acids, or short peptide groups, or sometimes non-peptide groups (called cofactors or prostethic groups), thus forming a bit branching strcture (kind of tree in CS), or be composed of multiple sub-units of the same or different type, that together create some weird complexes. All of them determine 3D structure, stability, folding and function. So the complexity is actually way higher than one would thing just by looking at the sequence. I don't belive sequence itself fully describe the protein. It does in many cases, but not always. Anyhow, biologists just want to know the structure of correctly folded protein for many reasons. Study of misfolding is rather niche, but of course important to some stuff, and progressing knolwedge of the folding process itself. Also I think the 10^143 figure, is just deceptive. It is not like nature tries all the combinations. Proteins are mosly synthetized in sequential process, one amino acid at the time, not in parallel, so obviously, the folding process is mostly incremental, and determined or rather influenced by the enzymes that do the synthesis - folding happens during synthesis naturally. It is like saying air molecules in the room I am in can be in one of 10^100000000000000000000000000000000 possible configurations, but it always finds the energy minimum and spreads uniformly. Or that there might be 10^1000000 books possible, yet humans, always write ones that do have a structure and sense and can be parsed. It silly to even mention this paradox, because it is not a paradox.

    This is a great video with a useful insight into how DeepMind came to win CASP. As a biochemist and bioinformatician who has been part of the effort to "solve the protein folding" problem I would say that strictly speaking the problem has not actually been solved. I say this because the research many people focused on was "how do proteins fold into specific configurations?" The DeepMind solution does NOT answer that question. There is no insight into the biophysical rules that guide the folding. And the reason that research has centred specifically on understanding "how" is because the answer to THAT question gives answers in BOTH directions of the problem. DeepMind can go from sequence to structure, but it cannot go from structure to sequence ("I want a protein that has this structure - what sequence gives me that?").
    Of course, with further AI and computing power, it is possible to start from a structure that has a similar form to what you wish to create and therefore it is just a matter of applying a genetic algorithm which does what it was created to mimic, to go through the combinations until the target structure is reached. But still, it isn't "understanding", it is just doing.
    The other thing I would say that DeepMind does not do is offer insight into diseases caused by misfolded proteins. And to be specific here, a misfolded protein is a protein that has not folded into the configuration that its sequence predicts to fold into, usually because of unusual factors within the folding environment. DeepMind can only go from sequence to structure. It cannot provide any information about the folding process or influences of the folding environment. For diseases where "misfolding" is due to sequence mutations strictly speaking the protein is folding correctly, just not the same as the native sequence. For these mutated sequences, yes, DeepMind will help.
    I have said for a long time that the problem of protein structure prediction would be broken by the brute force of AI. But the protein folding problem still exists.

    One of the better reports on this breakthrough, thanks Lex. In reality there are really only 20 naturally occurring proteinogenic amino acids since Selenocysteine which is homologous to cysteine replaces a Sulfur atom with Selenium and is only found in about 50 proteins. X-ray crystallography will still be around where there is a need to solve more complex protein structures where subdomains exist or to understand how small molecule drugs bind to protein targets. Maybe that will be the next breakthrough but a much tougher problem since there is not a big training set for AI. It will be interesting to know how well this methodology can be applied to predict variations in protein folding brought about by mutations in protein sequences and other important applications such as designer proteins if that is possible.
