I have some refs. on P450s.
I'm not certain of the location of a database, but a great place
to start looking is: http://sun2.lib.uci.edu/HSG/Ref.html
[let the *entire* URL load before you start clicking].
Of course, you could have found this link on my own modest page:
http://pw2.netcom.com/~drpauls/maths-f.html in the "General" category ;-)
