E1-E5 Property-Based Peptide Similarity Index PD for Two Sequences

Compute the PD sequence similarity index for two sequences:

where λj is the eigenvalue of the j-th E component, Ej(Ai) is the Ej value for the amino acid in the i-th position from sequence A, and Ej(Bi) is the Ej value for the amino acid in the i-th position from sequence B.
The first sequence should be shorter or equal to the second sequence. If the first sequence is shorter, then the first sequence is moved along the second sequence, one position at a time, and all PD values are reported.
Enter each protein sequence as a string of single-letter amino acid codes (the maximum length of the sequence is 1000). Sequences longer than 1000 amino acids will be truncated after the first 1000 amino acids. Gaps must be indicated by dashes (-). The symbols B, U, Z, X, *, and . are automatically converted to - (gap). Any other symbol will be deleted from the sequence, while the presence of other letters will trigger the stop of the computation.

Paste or type the first sequence


Paste or type the second sequence
