description
A derivative for the synthesis of sulfotyrosine-containing peptides by Fmoc-SPPS. Tyrosine sulfation is a post translational modification that occurs on integral membrane and secreted proteins and plays a crucial role in mediating biological processes. Thus, this derivative is useful for the study of site-specific tyrosine sulfation and its effect on peptide stability and activity. The sulfate group of FAA8485 is protected with a neopentyl (nP) group, which is stable to TFA. Neopentyl groups can be removed by treatment with aqueous ammonium acetate (1-2 M, 37 °C water bath, 6-12 hrs) or sodiumazide (50 eq, 70 °C, 16 h).
