The Dayhoff Mutation Data Matrix:
PAM 250 (point accepted
mutation)
An evolutionary distance of 1 PAM indicates the probability of a residue mutating during a distance in which 1 point mutation was accepted per 100 residues. The 250 PAM matrix gives similarity scores equivalent to 20% matches remaining between two sequences.

The Henikoff and Henikoff BLOSUM matrices:
BLOSUM 62 (BLOcks SUbstitution
Matrix)
A set of substitution matrices from blockes of aligned sequences in the BLOCKS database, in order to represent distant relationships more explicitly. 62% or greater cluster.
