Figure 5: Schematic models and the flop state molecular interaction models of (a) Cln1 (35-546)-Cdc28 (5-298) and (b) Cln2 (37-534)-Cdc28 (5-298). Ribbon; Cln1/2, Spacefilling; Cdc28. Gray region in schematic models is the cyclin box (Cln1; 101-189, Cln2; 103-191), blue and red in both schematic models and the flip state molecular interaction models is the extra amino acid region and the PEST motif, respectively.
