Sequence alignment of thermophilic ATPases (part 2). Sequence alignment of the C-terminal regions of the selection of ATPases from Table 1 as generated for Figure 1. The conserved Walker B sequence motifs are labelled below the alignment. The STIV2 B204 Walker B sequence motif is indicated with two asterisks above the alignment. Secondary structure elements of STIV2 B204 (PDB: 4KFU) are shown above the aligned sequences.
