To facilitate access to electronic resources for all researchers working in the field of P450 proteins and P450-containing systems, a WorldWide Web server has been established called The Directory of P450-containing Systems at <http://www.icgeb.trieste.it/p450/>. Currently it contains the most up-to-date list of sequences of both the P450 superfamily and proteins mediating electron transfer to P450, i.e. NADPH:P450 reductases, specific NAD(P)H:ferredoxin reductases, cytochrome b5 reductases, ferredoxins and cytochromes b5, and their homologues from different enzyme systems. All the referenced sequences are provided with accession numbers and cross-links to major sequence databanks: PIR, SWISS-PROT, EMBL/GenBank and PRF.
