Webb2 dec. 2024 · 3 minutes. Just as convincing images of cats can be created using artificial intelligence, new proteins can now be made using similar tools. In a report in Nature, … We optimized the combined objective function using simulated annealing starting from a random amino acid sequence of length L (L = 100 throughout this study). At each step i, a random single amino acid substitution is made at a randomly selected position, and the move is accepted based on the Metropolis … Visa mer The general protein design problem can be formulated in probabilistic terms as the finding of mutually compatible sequence–structure pairs such that the joint probability P(sequence,structure) is maximized. Using the … Visa mer Two-thousand proteins were generated using the hallucination procedure described above, and structurally compared to each other using the template modelling … Visa mer The trRosetta protein structure prediction network, described in detail elsewhere3, is a 2D residual-convolutional neural network that takes one- and two-site features derived from a multiple sequence alignment or a single … Visa mer Genes coding for the selected 129 designs were synthesized and cloned into pET28b(+) expression vector with an additional 21-residue … Visa mer

Webb5 jan. 2024 · Our hallucination approach greatly simplifies the protein design pipeline. By eliminating the need for templates, researchers can directly focus on creating a protein … Webb15 nov. 2024 · In the first “constrained hallucination” approach, we carry out gradient descent in sequence space to optimize a loss function which simultaneously rewards recapitulation of the desired functional site and the ideality of the surrounding scaffold, supplemented with problem-specific interaction terms, to design candidate immunogens …
Webb14 apr. 2024 · The constrained hallucination method works well for proteins with very little information provided i.e. only the functional site but is slow, due to an optimization procedure that must be performed for each protein that is designed.
