I realised this after writing the other report. the aiiA from the sequencing has two stop codons in a line TAA TAA this is very unusual and if I remembered rightly the aiia Dr fray sent us had one stop codon TAG so i ran a clustaw alignment between them and it is the aiia from the registry.
SeqA Name Len(nt) SeqB Name Len(nt) Score =========================================================== 1 regisrty 753 2 Fray 753 93 1 regisrty 753 3 Sequencing 754 100 2 Fray 753 3 Sequencing 754 93 ===========================================================
The aiia from Dr Fray is closley related (0.06640) as you would expect however the aiiA in J37034 is definitly from the registry.
Unfortunatly I cannot find any details about how J37034 was made so i can't work out how the aiiA got there.
