Hi Theresa, A well known method to investigate the surroundings of metals in proteins (metal-protein distances etc. ) is EXAFS (Extended X-ray Absorption Fine Structure). It has been implemented in quite a few specialized synchrtoron beam lines since the early 80s. I'm sure there's plenty of literature on the method and results on many metal proteins (I'm familiar with the EXAFS results on haemoglobin which caused quite a stir at the time).

Can metal distance be measured with time-resolved method (ligand binding and so on)? I knnow examples for materials like nanoparticles but how about proteins? Thank you.
