Figure 4. Electon density maps of mutant glutaredoxi. The electron density 2(F,j -IF,1 contoured at la for (a) a normal tyrosine Tyr7) and (b) Tyr85 for which the elecron density map indicates 2 conformations, (c) for a normal leucine (Leu85) and (d) the ensity for Leu55 indicating 2 conformations. Both conformations have been treated as haf occupied and no attempts hae ben made to refine the occupancies of the individual conformations.
