FIGURE 5.

A, deduced amino acid sequence alignment of fungal sesquiterpene synthases. The sequences of A. gallica protoilludene synthase (clone Pro1), Coprinopsis cinerea α-muurolene synthase (Cop3) and Cop5 (a sesquiterpene synthase with yet unknown product) are compared. Black boxes indicate identical residues for the three sequences; gray boxes indicate identical residues for two of the three sequences. B, a schematic presentation of the A. gallica protoilludene synthase genomic sequence with exons (shown as black boxes) and conserved DEXXD and NDxxSxxxE motifs.
