• PubMed Abstract: 
  

  MerF is a mercury transport membrane protein from the bacterial mercury detoxification system. By performing a solid-state INEPT experiment and measuring chemical shift anisotropy frequencies in aligned samples, we are able to improve on the accuracy and precision of the initial structure that we presented. MerF has four N-terminal and eleven C-terminal residues that are mobile and unstructured in phospholipid bilayers. The structure presented here has average pairwise RMSDs of 1.78 Å for heavy atoms and 0.92 Å for backbone atoms.
