Figure 2.

Alignment of deduced amino acid sequences of PaIDS1 (accession no. GQ369788) and selected additional conifer IDSs, including PaIDS2 (EU432047), A. grandis GPP synthase1 (AgGPPS1; AAN01133), AgGPPS2 (AAN01134), AgGPPS3 (AAN01135), PaIDS5 (EU432050), PaIDS6 (EU432051), and AgGGPPS (AAL17614). Identical amino acids are boxed in black. The artificial translation initiation site for PaIDS1 is indicated by a triangle. The Asp-rich motifs conserved among IDSs are indicated by the black lines. The amino acid sequence used for the generation of peptide antibodies is marked by the dotted line. Dashes indicate sequence gaps introduced to optimize the alignment.
