Comparison of the PCNA structures and PIP-box sequences. (a) Omit Fo − Fc difference map (blue mesh) calculated without the N-terminus of ApePCNA1 (orange) contoured at 2σ. The ICDL is colored green and red dashes represent hydrogen bonds. (b) Human PCNA with UHRF2PIP (PDB entry 5yco) is shown in the same orientation as in (a). (c) The PIP-box consensus sequence was compared with the N-terminal sequence of ApePCNA1 and proteins with the PIP-box sequence [PDB entries 1u7b (Bruning & Shamoo, 2004) and 2zvv (Strzalka et al., 2009)]. |
