Figure 4: Sequence alignment of AtClpD NTD with the NTD of putative ClpD from different plants.

The sequences have been aligned using ClustalW. For AtClpD, the residues forming helices are underlined and the helices are labelled α1 to α7. The residues conserved among all ten sequences are highlighted in red, those conserved among eight or nine sequences are highlighted in green and those conserved in five, six or seven sequences are highlighted in grey. The residues of regions that are substantially different in AtClpD structure as compared to ClpC have been given in blue. Bo, Cs, Gh, Nt, Rc, Vv, Os and Zm corresponds to Brassica oleracea, Citrus sinensis, Gossypium hirsutum, Nicotiana tabacum, Ricinus communis, Vitis vinifera, Oryza sativa and Zea mays respectively.
