Fig. 2

Amino acid sequence comparison of putative CPS and KS(L) from P. trichocarpa with characterized entCPS and KS from A. thaliana. Identical amino acids are marked by black boxes and amino acids with similar side chains are marked by gray boxes. Conserved motifs are labeled and the highly conserved DxDD and DxxDD motifs are boxed red. Asterisks indicate amino acids important for regulation and product specificity. Predicted N-terminal signal peptides are bold and an arrow indicates the truncation site for heterologous expression. AtCPS (Q38802), ent-copalyl diphosphate synthase; AtKS (Q9SAK2), kaurene synthase of Arabidopsis thaliana
