Figure 3

Surface depressions of the TA1238 and TA1434 trimers. The orientation and color scheme are the same as in Figure 2. (a) The surface of the TA1434 trimer is shown together with the cartoon of TA1238. The third monomer is visible fading away at the bottom. Active site residues Arg119 and Glu124 of TA1434 are at the bottom of the well-defined depression in the interface between the two monomers and are seen as blue and red patches. In TA1238, corresponding residues are isolated from the external solvent by the segment of the overhand connection of one monomer (blue) and by the β hairpin of the other (pink). (b) The surface of the TA1238 trimer is shown together with the cartoon of TA1434. The wide open depression is blocked by the overhand connection (see also Figure 2) and is transformed into a very narrow cleft. (Figure was generated with PyMol, www.delanoscientific.com.)
