To introduce persistent homology frameworks for extracting molecular topological fingerprints to characterize protein structure, flexibility, and folding stability.
Extracted molecular topological fingerprints (MTFs) using all-atom and coarse-grained representations alongside a slicing method to trace the geometric origins of topological invariants.
Developed cutoff-like and correlation matrix-based filtrations using accumulated bar lengths to model protein rigidity, connectivity, and B-factor characteristic distances.
Benchmarked topological evolution and folding stability predictions directly against molecular dynamics simulations.
Accurately identified optimal cutoff distances for elastic network models and characteristic distances in protein B-factor flexibility analysis.
Achieved strong qualitative and quantitative consistency between topological fingerprint predictions of folding pathways and molecular dynamics simulation data.
