Figure 4 The three distinct ligand-binding sites of the PCNA123
trimer. The front face of the trimeric ring is shown as an
electrostatic charged surface with the C-terminal fragment of
Pol IV modeled in the three distinct ligand-binding sites. The
binding sites are mapped by ribbon-styled C-termini with the
side chains as white mesh surfaces. The modeling was performed
by superposing the PCNA123 trimer with the -clamp-PolIV-LF
complex (PDB code 1ok7 ; Bunting et al., 2003[Bunting, K. A.,
Roe, S. M. & Pearl, L. H. (2003). EMBO J. 22, 5883-5892.]).
