Saccharomyces cerevisiae squalene epoxidase contains two highly conserved motifs, 1 and 2, of unknown function. Amino acid substitutions in both regions reduce enzyme activity and/or alter allylamine sensitivity. In the homology model, these motifs flank the flavin adenine dinucleotide cofactor and form part of the interface between cofactor and substrate binding domains.
