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 in the next few days and weeks. Only
BLASTP works now since this is a protein database. The server address is

Arabidopsis P450 genes by chromosome
These genes are placed in the order that the clones appear
on the chromosomes. This is a P450 map without the map. Updated Jan. 2, 2001

This table cross references the chromosome assignment gene names
To the cytochrome P450 names. There are 47 P450s on this chromosome.

What's New May 12, 2000
A second revised tree of the 86 and 94 families is posted. It includes 86D2, a
new P450 in Arabidopsis. See newest 86 and 94 family tree The 86Ds shifted to the
94 family and will be renamed as 94D sequences

What's New Sept. 13, 1999
Incyte pharmaceuticals deposited 7938 Arabidopsis ESTs in Genbank on Sept. 8. I have
looked at them by Blast searches over the weekend and I found 53 that contain P450
sequences. 44 of these are close or exact matches to known P450s from Arabidopsis (96%
or better identity). One matches a new confidential sequence CYP78A9. Nine ESTs are
new sequences that range from 60% to 93% identical to known P450s. see New Arabidopsis ESTs
What's New May 20, 1999
A possible chloroplast P450 has been reported from almond this sequence is probably in
the CYP71D subfamily. Therefore, the whole 71D subfamily might be localized in the
chloroplast. This is not an Arabidopsis sequence, but it is news.
What's New Mar. 2, 1999
The CYP72 family has been sequenced (accession number AB023038) and there are 8
genes and one pseudogene present. This is similar in size to the Z97338 gene cluster of
CYP702 and 705 genes that has 8 genes and two pseudogenes. The spacing between the
genes is less than 1000bp except for one gap of about 6000bp. See the nomenclature files
for nucleotide positions. The sequences have been placed in the FASTA Arabidopsis file.
What's New Feb. 25, 1999
An estimate has been made for the number of P450 genes in Arabidopsis (372) see P450s
sorted by family.
What's New Feb. 23, 1999
Nine new P450s have been named and an alphabetical list of P450 Accession numbers has
been made see above.
What's New June 11, 1998
Ten new Arabidopsis sequences are released in Genbank on June 9. These are from
D78598 to D78607 and represent previously confidential sequences.
What's New May 8, 1998
There is a list of 86 GSS genome survey sequences for Arabidopsis P450s. These
are being added to the Arabidopsis P450 protein translation list above.
What's New April 21, 1998
I have searched for new cytochrome P450s in Arabidopsis and find 83 full length
P450s. There are also 228 ESTs for Arabidopsis P450s.
I have now named most of these sequences and they are included in the files above.
