Figure 2.
Figure 2 Comparison of pKinI with the most structurally similar gliding motor NCD. Common elements are shown in gray, differing pKinI parts in red and differing NCD parts in blue. The sulfate ion that marks the -phosphate of ADP is shown in yellow. The largest differences are the length of L2, the positioning of the 'tip' (L6 and L10), the direction of L8 and the unusual stability of the switch II region (L11- 4).
