Protein Mutant Database

Provides a compilation of protein mutant data, providing information on functional and/or structural influences brought about by amino acid mutations at specific positions of a protein. PMD is an online resource is unique in two respects: (i) almost all proteins are included, except for natural mutants of the globin and immunoglobulin families; (ii) natural as well as artificial mutants are covered, including random and site-directed mutants.
