Figure 6
X-ray crystal structures of (a) Y149A-Hsp72 in complex with ADP (PDB entry 7f4z) and (b) Y149A-Hsp72 in complex with AMPPnP (PDB entry 7f50). The colour scheme is the same as in Figs. 2 and 3. The side chain of Tyr149 and water cluster 3 of the superposed joint XN structure (PDB entry 7f4x) are shown as a semi-transparent stick model. |
