Two examples of linear motifs packed into structured domains. a) PDB 2D07: Sumo-interacting motif (orange) of TDG domain (green) bound to SUMO-3 protein (cyan); b) PDB 2PTK: closed conformation of the proto-oncogene tyrosine-protein kinase Src. Blue: SH2 domain; red: SH3 domain; green: protein kinase; orange: pTyr-527; yellow: linkers; yellow spheres: SH3 binding peptide. All structure views were prepared with PyMOL http://www.pymol.org/ webcite.
