PAM matrices were introduced by Margaret Dayhoff in 1978. The calculation of these matrices were based on 1572 observed mutations in the phylogenetic trees of 71 families of closely related proteins. The proteins to be studied were selected on the basis of having high similarity with their predecessors. The protein alignments included were required to display at least 85% identity. As a result, it is reasonable to assume that any aligned mismatches were the result of a single mutati… WebMargaret Dayhoff, one due to Kimura (1983, p.75) which approximates it based simply on the fraction of similar amino acids, and one based on a model in which the amino acids …
