Figure 5.
Figure 5 Stereoviews of the T3-PB1 groove regions of (a) Pel-15 and (b) Ech-PelC (PDB entry [202]1air ). The location of this region is shown in Fig. 1[203] [link]-[204][turqarr.gif] . Amino-acid side chains are represented by stick models. The calcium ion and amino-acid side chains in the pH 9.5 structure are represented by a yellow sphere and red sticks, respectively. The conformations of those amino-acid side chains are changed by attachment of the calcium ion.
