Figure 2. Stereo view of the (F[o] -F[c]) electron density
map around the N-terminal residue Tyr501. The N terminus (Tyr501
to Arg503) of rTAP (yellow) is locked into the active site of
factor Xa (atom type) to form a complex with rTAP. The phases
were calculated without the coordinates of the first three
N-terminal residues of rTAP. The electron density map was
contoured at 2.5 s.
