Figure 1.
Fig. 1. The active site of ASV IN (catalytic core domain). A, F[o] F[c] difference density "omit" map, contoured at 2.5 , showing the position of the side chain of D64N (blue) compared with the side chain of Asp-64 (brown) in the active conformation. The hydrogen bonding pattern of a structurally conserved water molecule observed in all ASV IN structures is also shown. B, hydrogen bonding of the side chain of D64N with Asn-160. The hydrogen bonding pattern of a structurally conserved water molecule observed in all ASV IN structures is also shown. C, hydrogen bonding of the side chain of Asp-64 with the structurally conserved water.
