Protein Structure Predictions

Protein Structure Predictions

We have created a protein structure prediction pipeline (PSPP) that uses state-of-the-art software deployed on DoD high-performance computing assets to predict the three-dimensional structure of a protein from its amino acid sequence. The methods included in the pipeline include homology modeling and ab initio prediction algorithms. Access to three-dimensional structures of novel protein sequences is crucial for rapid in silico drug screening, assessment of vaccine development, understanding enzymatic reactions, and modeling protein interactions.
