Figure 4. Molecular surface of Form II EcHsp31 with the linker region from Form I EcHsp31 superimposed to show how Tyr 29 limits access to the active site pocket. The surface of Form II EcHsp31 is colored by domain--A (blue), and P (green), and Cys 185 (yellow). Regions D2 and D3 are modeled in red and orange ball and stick representation from their relative position Form I EcHsp31 structure. Close-up view of the access to Cys 185 of the triad is shown for both Form I and Form II.
