Figure 3
SsoPCNA3 is displaced from the ring relative to the observation for the huPCNA homotrimer (PDB code 1vym
; Kontopidis et al., 2005). The SsoPCNA trimer is coloured as in Fig. 2(a); the human trimer is coloured cyan, wheat and pale pink. The same displacement is seen when compared with the yeast homotrimer (Krishna et al., 1994). The structures are shown in stereoview. |
