The CYPome (Cytochrome P450 complement) of Aspergillus nidulans

The cytochromes P450 (CYPs) are found in all biological kingdoms and genome sequencing projects continue to reveal an ever increasing number. The principle aim of this paper is to identify the complete CYPome of Aspergillus nidulans from the genome sequence version AN.3 deposited at the Broad institute, assign the appropriate CYP nomenclature and define function where possible. The completed analysis revealed a total of 111 CYP genes, 3 of which were previously unknown and 8 pseudogenes. representing 89 CYP families, 21 of which are unique. We have identified 28 potential gene clusters associated with one or more CYP genes and discussed those with putative PKS and NRPS associated function. The chromosomal location of the genes, predicted cellular location of the proteins and possible function(s) are discussed. (C) 2008 Elsevier Inc. All rights reserved.
