Figure 4

CPK presentation of the crystal structures of apo E. coli Trpases and holo P. vulgaris (a) mutant C298S (shown in magenta), (b) mutant Y74F (shown in orange), (c) apo wt E. coli (shown in blue) and (d) holo P. vulgaris Trpase (gray). This indicates that the two apo mutants of E. coli Trpases as well as the wt Trpase are found in an open conformation, different from the closed conformation found for P. vulgaris in its holo form.
