Figure 4. Putative secondary metal binding sites in Δ6-protoilludene synthase homologs are located at positions that are variable.

Figure 4

The evolutionary conservation of amino acids among putative trans-humulyl cation (7) producers is displayed upon a structural model of Stehi73029. The conserved active site motifs, and sites that were mutated in Stehi73029 are shown as sticks and residues are labelled. Evolutionary conservation of sites across Basidiomycota homologs is colored coded from turquoise (variable) to magenta (conserved).
