====== Beyond arthropods : a few reference CYPomes ====== * Human CYPome {{ ::57humanp450s.fasta |57 human P450s}} * //Saccharomyces cerevisiae// CYPome {{ ::3yeastp450s.fasta | 3 yeast P450s}} * //Arabidopsis thaliana// CYPome {{ ::a_thaliana.fasta |244 Arabidopsis P450s}} * //Escherichia coli// is a major model organism lacking P450 genes. The distribution of P450s in bacteria is highly uneven, for instance all cyanobacteria and mycobacteria have P450 genes, most firmicutes, bacteroidetes and gammaproteobacterial species have none (Nkosi et al. 2022).
