A BLAST server has been set up on a RedHat Linux machine to allow blast searching of selected P450 sets. The first set available is all the Arabidopsis P450s, 273 named genes and 16 more unnamed fragments that have not been designated because I do not know if they are really different from the named genes. We plan to add more P450 sets (human , mouse, Neurospora) in the next few days and weeks. Only BLASTP and BLASTX work now since this is a protein database. The server address is http:/132.192.64.52/p450.html GO THERE NOW
