Abstract: A method in a computer system for modeling a three-dimensional structure of a model protein is provided. In one embodiment, the modeling is based upon a three-dimensional structure of a template protein and an amino acid sequence alignment of the model protein and the template protein. For each amino acid in the model protein, when the template protein has an amino acid aligned with the amino acid of the model protein, the position of the backbone atom of the amino acid of the model protein is established based on the position of a topologically equivalent backbone atom in the aligned amino acid of the template protein. In another embodiment, the modeling of a variable region of the model protein is based on a collection of .psi. and .phi. angle values for amino acid pairs in a family of proteins. In a further embodiment, these .psi. and .phi.

Abstract: A method in a computer system for modeling a three-dimensional structure of a model protein is provided. In a preferred embodiment, the modeling is based upon a three-dimensional structure of a template protein and an amino acid sequence alignment of the model protein and the template protein. The proteins comprise a plurality of amino acids having backbone atoms and side chain atoms. For each amino acid in the model protein, when the template protein has an amino acid aligned with the amino acid of the model protein, the position of each backbone atom of the amino acid of the model protein is established based on the position of a topologically equivalent backbone atom in the aligned amino acid of the template protein. The inter-atomic distance constraints for each pair of atoms with an established position is generated. Finally, the position of each atom in the model protein is set so that the inter-atomic distances are in accordance with the constraints.
