If two DNA sequences are very similar (or identical) then the hypothetical 
protein sequences from all six pairs of frames are also going to be very 
similar (or identical). Presumably you can figure out which frame is 
correct by finding a homologous PROTEIN sequence (BLASTX) or by looking at 
stop codons?

If by this you mean a database of transposon tagged loci, then the 
Arabidopsis Transposon Insertion Database (ATI) might be useful:


Hope this helps!
