Identification of tyrosine O-sulfate in proteins by reverse-phase high-performance liquid chromatography: use of base hydrolysis combined with precolumn derivatization using phenyl isothiocyanate
A procedure has been developed for the analysis of tyrosine O-sulfate in proteins. Samples are subjected to base hydrolysis with Ba(OH)/sub 2/, neutralized with sulfuric acid, and the majority of other amino acids removed by chromatography on Dowex AG 50 x 8. The average recovery of tyrosine O-sulfate from these procedures was 43%. Tyrosine O-sulfate was identified by reverse-phase HPLC as the phenylthiocarbamyl derivative following precolumn derivatization with phenyl isothiocyanate. The method has been applied to bovine fibrinogen giving a tyrosine O-sulfate content ranging from 0.59 to 1.23 mol/mol. These procedures were also shown to be suitable for the analysis of the incorporation of (/sup 35/S)sulfate into tyrosine O-sulfate residues in proteins by intact cells.
