The structures and mechanism of action of many terpene cyclases are known, but there are no structures of diterpene cyclases. Here, we propose structural models based on bioinformatics, site-directed mutagenesis, domain swapping, enzyme inhibition and spectroscopy that help explain the nature of diterpene cyclase structure, function, and evolution. Bacterial diterpene cyclases contain ∼20 α-helices and the same conserved “QW” and DxDD motifs as in triterpene cyclases, indicating the presence of a βγ barrel structure. Plant diterpene cyclases have a similar catalytic motif and βγ-domain structure together with a third, α-domain, forming an αβγ structure, and in H+-initiated cyclases, there is an EDxxD-like Mg2+/diphosphate binding motif located in the γ-domain. The results support a new view of terpene cyclase structure and function and suggest evolution from ancient (βγ) bacterial triterpene cyclases to (βγ) bacterial and thence to (αβγ) plant diterpene cyclases.
