WebThe "Hybrid Protein Model" (HPM) is a fuzzy model for compacting local protein structures. It learns a non-redundant database encoded in a previously defined structural alphabet composed of 16 protein blocks (PBs). The hybrid protein is composed of a series of distributions of the probability of observing the PBs. The training is an iterative … WebThe primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique... smallbox company
