• Each of the following 449 sequences has E-value less than 10.
• The E-value of a sequence is the expected number of sequences in a random database of the same size that would match the motifs as well as the sequence does and is equal to the combined p-value of the sequence times the number of sequences in the database.
• The combined p-value of a sequence measures the strength of the match of the sequence to all the motifs and is calculated by
  • finding the score of the single best match of each motif to the sequence (best matches may overlap),
  • calculating the sequence p-value of each score,
  • forming the product of the p-values,
  • taking the p-value of the product.
• The sequence p-value of a score is defined as the probability of a random sequence of the same length containing some match with as good or better a score.
• The score for the match of a position in a sequence to a motif is computed by by summing the appropriate entry from each column of the position-dependent scoring matrix that represents the motif.
• Sequences shorter than one or more of the motifs are skipped.
• The table is sorted by increasing E-value.
