There are now 69 N-terminal sequences in an alignment under the Drosophila button on the main page. That means there are at least that many P450s in Drosophila and probably a few more will be found, since C. elegans had 80 P450s. The FASTA file of P450 sequences has all the fragments I have so far assembled and 50 full length sequences are available there. This file is a working scratch pad, so bear with me until I get them all in final order. There are a
couple of sequences that are so different from existing P450s that I have not been able to assemble the middle section, even though it is present in the sequence data, I cannot identify the exons.
