Designer enzymes open up a range of possibilities, but ultimately each enzyme performs one specific task. A living organism consists of countless complex interacting signaling pathways and feedback systems, working together to maintain homeostasis. To recreate such a system, protein designers needed to find a way to make proteins with two stable conformations.

Straightaway the AI designed new molecules that also increase the activity of PPARs, like the drugs currently available, but without a lengthy discovery process. After the ETH researchers had produced these molecules in the lab, colleagues at Roche subjected them to a variety of tests. These showed that the new substances are indeed stable and non-toxic right from the start. The information in this press release should be considered accurate only as of the date of the release.

PvP was the first company launched through the University of Washington’s Translational Investigator Program. Takeda Pharmaceuticals fronted the money to conduct phase 1 clinical trials on the novel enzyme, called KumaMax, and in February 2020 exercised its option to acquire PvP. The University of Washington’s Institute for Protein Design has become a hub to galvanize de novo protein engineering, citizen science and much more since its founding in 2012. Bioactive PeptidesChemically synthesized molecules with predictable structures and functions. Advanced Drug DeliveryNanoscale protein assemblies that move therapeutics to specific cells within the body.
Real-World Applications of Protein Design
For larger complexes involving multiple different subunits, the team was able to detect the configuration of the proteins in the complex using a mass spec technique called surface-induced dissociation. By slamming the molecules into a surface to break apart the subunits and then measuring which subunits colocalized among the resulting fragments, they could see how the subunits were arranged in the large complex. This type of structural characterization provides critical information to verify whether synthetic protein complexes are forming the way the designers expect. Today IPD lists seven ongoing projects to address the pandemic, from designing nanoparticle vaccines and anti-inflammatory proteins to screening existing drugs. Through Baker’s hypercollaborative nature and his desire to distribute the technology for broad adoption, de novo protein design may one day become a part of every protein engineer’s toolbox. Ben graduated from Johns Hopkins University with his Bachelors in Biophysics and a minor in Computer Science.

The accent brown-copper gradient color was chosen to represent the chocolate flavor of this particular variant. After exploring several options, I have chosen the preferred version of the design. Alt-protein companies that have successfully scaled to IBRL’s current capacity will then need to find a commercial production facility, which often requires them to build a new facility, Jacobson said.

A great label shows the world what you stand for, makes people remember your brand, and helps potential customers understand if your product is right for them. Labels communicate all of that through color, typography and other design elements. A bold label design for a plant protein would likely involve bright, eye-catching colors and typography to capture consumers' attention. The design would also need to clearly communicate the benefits of the plant protein and appeal to consumers looking for healthy, sustainable protein options. The result would be a striking label design that stands out on the shelf and effectively communicates the product's value to consumers.
targeting function
No longer limited to describing and copying nature’s proteins, protein designers have learned to build sets of proteins that can change conformation on demand or carry out multi-step instructions, such as toggling between two states. Chemistry plays a vital role in protein design by helping researchers understand the forces and interactions that govern protein folding. Protein folding refers to the process by which a linear chain of amino acids folds into a three-dimensional structure, which determines its function. Understanding the rules of protein folding allows us to design proteins that adopt their intended structures and exhibit desired functions. KumaMax successfully adapted an existing enzyme to perform a new function, but in some cases, success requires assembling available parts into something completely new.

Computational Protein Design
The Cochran Laboratory uses interdisciplinary approaches in chemistry, engineering, and biophysics to study and manipulate complex biological systems, with a focus on developing new technologies for basic science and biomedical applications. In addition, combinatorial and rational methods are used to engineer designer protein and peptide ligands for a variety of applications including wound healing, cardiac tissue engineering, and cancer imaging and therapy. Until recently, however, the discovery of binding proteins depended on the serendipity of high-throughput experimental screening and animal inoculations.

In February, Rosetta successfully predicted the 3D structure of the SARS-CoV-2 spike protein, which allows the virus to gain access to human cells. The flurry of effort that accompanied the project crashed some of the networked computers, but with the protein structure now in hand, work is underway to fight the disease. Researchers crafted mini-protein binders that perfectly complement the spike protein, preventing it from latching onto cellular receptors. To make a vaccine, IPD researchers are attaching the spike protein to a synthetic virus-like particle. The particle displays the spike protein in a repetitive array, an arrangement designed to stimulate a vigorous immune response. Researchers at the University of Washington’s Institute for Protein Design (IPD) don’t like to work alone.
By leveraging the power of computational modeling, our researchers are creating solutions to some of the most pressing challenges in medicine, technology, and sustainability. Advanced computational techniques, including novel machine learning algorithms, allow our scientists to model the behavior of proteins at the atomic level. This knowledge helps researchers generate novel proteins with optimized stability, binding affinity, or catalytic activity. The principles of physics play a crucial role in protein design, particularly in the development of computational models and simulations. By applying concepts from statistical mechanics, thermodynamics, and molecular dynamics, researchers can predict how a protein will fold and interact with other molecules in its environment.
"Our work has made the world of proteins accessible for generative AI in drug research," Schneider says. "The new algorithm has enormous potential." This is especially true for all medically relevant proteins in the human body that don't interact with any known chemical compounds. Protein design weaves together principles from biology, chemistry, and physics, allowing researchers to create novel molecules with remarkable precision and functionality. In recent years, machine learning has proven to be a powerful way to model and design proteins on the computer. Rather than having human experts try to encode their knowledge into software, this strategy allows computers to train themselves to detect patterns in proteins. Recognizing the impact of this innovation, the journal Science dubbed the application of machine learning to protein science their 2021 Breakthrough of the Year.
Mother Nature has created some incredible tools, but those solutions have come about as a result of evolutionary pressures, including the need to conserve genetic real estate by making proteins that serve multiple functions. Whereas a natural protein may be the solution that evolution has arrived at, it may well not be the most efficient tool for a task thought up by a human. Creating new proteins, Baker says, allows the tools to be specifically directed, as well as modular and customizable to other uses. El-Samad’s return to San Francisco commenced “an intense and beautiful” collaboration, in which Baker’s team would send her computationally derived protein sequences and her lab would synthesize the proteins and test them. “It was very clear from the get-go that thing was going to work,” recalls El-Samad.
