摘要
Amino acid residues are under various kinds of local environmental restraints, which influence substitution patterns. Ulla,(1) a program for calculating environment-specific substitution tables, reads protein sequence alignments and local environment annotations. The program produces a substitution table for every possible combination of environment features. Sparse data is handled using an entropy-based smoothing procedure to estimate robust substitution probabilities.
