Figure 4
Views of difference electron density in the vicinity of the NAGn-binding sites on HEWL. (a) NAG2 on HEWL at σ = 2. (b) NAG3 on HEWL at σ = 1.5. The end left and right saccharide rings are partially filled (35 and 65%, respectively). (c) NAG4 on HEWL at σ = 1.5. (d) NAG5 on HEWL at σ = 1.5. (e) NAG6 on HEWL at σ = 1.5. (f) A view of the A–E binding of NAG5 to HEWL. These figures were prepared with PyMOL (DeLano, 2004). [Reproduction of Figs. 1 and 7 in Von Dreele (2005).] |
