  • Notably, the biological function of the attached ubiquitin chain depends on which lysine residue is used for chain formation. (uni-konstanz.de)
  • Nitration of Hsp90 induces cell death " describes how nitration as a result of oxidative stress can turn a normally helpful protein into a toxic protein. (bmglabtech.com)
  • Protein phosphatase 4 (PP4) plays an indispensable regulatory part in the development and malignant progression of multifarious tumors. (bvsalud.org)
  • where M i is a floating point number (potential modification mass in Daltons) and X i is a single letter abbreviation for a type of amino acid residue. (thegpm.org)
  • Mass-spectrometric evaluation of affinity-purified stalled spliceosomes indicated how the intermediates differ in proteins structure both from one another and from previously characterized indigenous A and B splicing complexes. (gasyblog.com)
  • To your knowledge none of the few small-molecule inhibitors of pre-mRNA splicing have already been utilized to isolate the stalled splicing complexes for even more evaluation like the dedication of proteins structure by mass spectrometry. (gasyblog.com)
  • Consequently, a lot of effort is put into identifying the constituent proteins using mass spectrometric methods. (lu.se)
