Figure 3

Multiple sequence alignment of C-terminal RecA-like domains from related RNA helicases with Hera_208–510. Conserved residues are in bold, similar residues are boxed and helicase signature motifs as defined in Linder (2006 ▶) are underlined. The percentage similarity and identity for the displayed sequence region are given at the end of the alignment. The sequences are labelled with their PDB codes. 1hv8, M. jannaschii RNA helicase (Story et al., 2001 ▶); 2hjv, B. subtilis YxiN (Caruthers et al., 2006 ▶); 1fuk, yeast initiation factor 4A (Caruthers et al., 2000 ▶); 2g2j, human DDX25 RNA helicase (L. Lehtio et al., unpublished work); 1xti, human UAP56 (Shi et al., 2004 ▶). None of these structures proved useful as a molecular-replacement model. The figure was created using ESPript (Gouet et al., 2003 ▶).
