Crystal Structures of the Putative Isocitrate Dehydrogenase from Sulfolobus tokodaii Strain 7 in the Apo and NADP⁺-Bound Forms

Figure 2

Multiple alignment of sequences for ST2166, ApIDH, and EcIDH. The secondary structure elements were indicated and labeled as helical lines and A to K for α-helices and as solid arrows and a to m for β-strands, whose nomenclature was proposed by Hurley et al. [2]. Identical residues were shaded in red; similar residues were colored in red.
