All Drosophila melanogaster P450 protein sequences have been posted as a FASTA
File All Drosophila melanogaster P450s
These sequences are all in Genbank. There are no confidential sequences left.
There are 86 P450 genes and 4 pseudogenes. CYP51 is absent. Since CYP51 is
also absent in C. elegans, this important eukaryotic sterol biosynthetic gene
may have been lost in the common ancestor of flies and nematode worms.
