Why not try BLAST? It is my understanding that this program (Basic
Local Alignment Search Tool) is particularly useful for finding matches
between small peptide stretches.

Situation:  you have multiple peptide sequences _from the same 
protein_ , but their order is not known.  Each sequence is short (say
6-10 aa).  What database search tool, if any, can accept this sort of
data?

I already did a trial run with the Drosophila white gene, where I took
three peptide chunks and made one test sequence out of them (like 61-70
+
101-110 + 151-160 = sequence, although I don't recall the exact
numbers). 
I ran this through Genbank's FASTA, but it only matched the best
subregion
and did not align (with gaps) the other two.  I sent the same thing to
BLAZE, but it hasn't answered yet, so no info on that.

Any suggestions?
