Engineering Contradiction Analysis
1Measurement precision
If traditional methods like X-ray crystallography and analytical tests are used to determine protein structure and properties, then measurement precision is improved, but productivity deteriorates due to the time-consuming and costly nature of the process
Solution Approach 1:
The patent applies preliminary action by training machine learning models in advance using known protein structures and properties from the PDB database. Once trained, these models can rapidly predict structures and properties of new proteins without requiring time-consuming experimental methods, thus resolving the contradiction between measurement precision and productivity
Solution Approach 2:
The patent uses copying by creating computational models that replicate the information contained in experimentally determined protein structures. These models serve as virtual copies that can be analyzed instantly, avoiding the need to perform actual physical experiments on each protein, thereby increasing productivity while maintaining accuracy through the trained models
2Measurement precision
If multiple analytical tests are performed to characterize protein properties, then measurement precision is improved, but loss of time increases significantly
Solution Approach 1:
The patent merges multiple analytical tests into a single integrated machine learning prediction system. Instead of performing separate experimental tests for each protein property, the trained models simultaneously predict multiple properties (structure, stability, molecular weight, etc.) in one computational pass, dramatically reducing time loss while maintaining measurement precision through the comprehensive training data
3Productivity
If machine learning models are used to predict protein structure and properties, then productivity is improved, but measurement precision may deteriorate due to potential inaccuracies
Solution Approach 1:
The patent implements feedback by training the machine learning models on experimentally verified protein data from the PDB database. The models learn from the ground truth data and can be continuously refined by comparing predictions with actual experimental results, ensuring that productivity gains do not compromise measurement precision. The feedback loop allows the system to correct inaccuracies and improve over time

AI summary
Technologies are described related to determining protein structure and properties based on sequences of proteins. In various implementations, a first model can be generated to determine structural features of proteins based on amino acid sequences of the proteins. Additionally, a second model can be generated to determine biophysical properties of proteins based on structural features of the proteins. In particular implementations, an amino acid sequence of a particular protein can be utilized by the first model to determine one or more structural features of the protein. The one or more structural features of the protein generated by the first model can be utilized by the second model to determine at least one biophysical property of the protein.
