A Sulfated, Phosphorylated 7 kDa Secreted Peptide Characterized by Direct Analysis of Cell Culture Media

An unusual sulfotyrosine-, phosphoserine-containing motif was mapped on a differentially post-translationally modified 60 residue antimicrobial neuroendocrine peptide called chrombacin. The study was performed by high resolution FT MS using complementary fragmentation techniques. The peptide was ana...
