Figure 2. Two nucleozin molecules found in the asymmetric unit.

NP molecules were shown as carton while nucleozin and key interaction residues were shown as stick models. Nulceozin omit map was shown as green mash at 2σ. (A) Nucleozin between chains A and B; (B) Nucleozin between chains C and D; (C) No nucleozin found between chains F and E. The Y289/N309 pocket in chain F was about 40 Å away (red dashed line) from the R383/R384 pocket in chain E.
