Clicked Europium Dipicolinate Complexes for Protein X-Ray Structure Determination.

  • Primary Citation of Related Structures:

  • PubMed Abstract: 

    New trisdipicolinic acid-lanthanide complexes are reported as phasing agents for X-ray crystallography of proteins. It is demonstrated that CuAAC modifications allow protein co-crystallization with low concentration of lanthanide complexes leading to an accurate structure determination.
