Query sequence 1ybvA aligned with the optimal sequence drawn from the PSI-BLAST profile The optimal sequences generated from the PSI-BLAST alignments have large stretches of tryptophan repeats that show where the profile has lost evolutionary information. Here the query sequence (above) is aligned with its optimal sequence. Repeated tryptophans in the optimal sequence are highlighted in blue.
