Figure 2.
Fig. 2. The stereo view of the molecular conformation of H[2]TPPS in the asymmetric unit of the crystals of the H[2]TPPS·ConA complex. A, the F[o] F[c] map in the ligand-binding site on ConA, scaled at 3.2 , showing half of the H[2]TPPS molecule corresponding to the asymmetric unit. The porphyrin model has been built into the map (thick black lines). The water molecules in the region have also been shown as black spheres. The surrounding ConA residues are shown as thin gray lines. B, a stereo view of the porphyrin conformation as it appears in complex with ConA molecule. The non-carbon atoms belonging to one asymmetric unit are labeled.
