Deep Learning for Protein Crystallography: Improving Structure Determination

What is it about?

The application of deep learning techniques in protein crystallography has shown promise in improving all stages of protein structure determination. These techniques can provide automated and efficient approaches to protein crystallography, leading to significant advancements. However, deep learning models face challenges in handling the multi-stage process of protein structure determination through crystallography, and there is a risk of bias in training data. Recent trends involve the use of synthetic data sets for supervised learning, which may result in better-performing models when compared with models fine-tuned with real data. A good-quality data collection, assessment and labeling workflow is crucial in ensuring the model's robustness, reliability and reproducibility.
