Figure 6. Thr106 of p38 plays a crucial role in the p38-SB inhibitor interactions. (a) In the native p38 structure, Thr106 forms an interaction with a water molecule. (b) In the p38-inhibitor complex, Thr106 rotates around x1 for about 120° and participates in the nearby hydrogen-bonding network that also involves His107. b strands in the N-terminal domain are colored green.
