Characteristics of TRP-2_{(180–188 )} APLs bound to HLA-A*0201 molecules

Peptide	Sequence	Distance (Å) (P2–P9)a	Orientation of side chain (P9)b
TRP-2 2L	SLYDFFVWL	19.15	↓
TRP-2 2M	SMYDFFVWL	19.20	↓
TRP-2 1Y2L	YLYDFFVWL	19.53	↓
TRP-2 1Y2M	YMYDFFVWL	19.53	↓

^aThe distance between P2 and P9 and the orientation of the side chain at P9 was determined by the Simulation Method as described in Fig. 1

^bArrows indicate the orientation of P9 residues with the respect to the floor of the binding groove of HLA-A*0201
