• PubMed Abstract: 
  

The three-dimensional crystal structure of the triple-point mutant of the catalytic subunit of human protein kinase CK2alpha has been determined at 2.4 A resolution. Microcrystals of mutant CK2 catalytic subunit were obtained by a protein-crystallization method based on thin-film nanotechnology. These microcrystals (of about 20 micro m in diameter) were used for diffraction data collection by means of the microfocus beamline at the ESRF synchrotron. A comparison between the human protein kinase CK2alpha and the corresponding enzyme from a lower organism (Zea mays) is made.
