#Question id: 664


Which is evidence that structures for proteins determined by X-ray crystallography represent the structures in solution?

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. Their similarity to structures determined by NMR.

  2. The protein crystals are soluble in water.

  3. The proteins must align in a regular pattern to form a crystal.

  4. Only one conformation is ever possible for a protein so it is irrelevant whether the protein is in a crystal or in solution.
