Figure 3: Molecular interaction models of (a-1) the flip state, (a-2) the flop state of Cln1(101-189)-Cdc28(5-298), (b-1) the flip state, (b-2) the flop state of Cln2(103-191)-Cdc28(5-298). Spacefilling model with brown is Cdc28. Ribbons are Cln1 and Cln2. Regions as the extra amino acid region, lα-3, α-4, and α-5 helix are indicated as blue, green, cyan and purple, respectively.
