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 (3-D) structure of a protein from its amino acid sequence. We aim to utilize this pipeline to rapidly screen drugs in silico, assess vaccine development, understand enzymatic reactions, and model protein interactions, all of which require access to the 3-D structure of novel protein sequences.
