Figure 4.
FIG. 4. Structural changes of Neu2 upon maltose and DANA binding. a, ribbon diagram of Neu2 apo form, viewed from the side. The active site is located on the top part of the protein. Secondary elements are colored as in Fig. 2. b, Neu2 sugar-induced form in the same orientation as in a. The arrow indicates the loop containing Glu111 that becomes ordered and forms helix 2. c, Neu2-DANA complex in the same orientation as in a. DANA is represented as a ball-and-stick model. The arrows indicate two helices ( 1 and 2) that are formed upon inhibitor binding.
