3,5-Difluoro-L-tyrosine is a functional, tyrosinase-resistant mimetic of tyrosine. 3,5-Difluoro-L-tyrosine can be used to analyze the substrate specificity of protein tyrosine phosphatases (PTPs)[1].
3,5-Difluoro-L-tyrosine (F2Y) is a fluorinated tyrosine analog. 3,5-Difluoro-L-tyrosine is compatible with every aspect of library synthesis, screening, and sequence identification. 3,5-Difluoro-L-tyrosine is a good functional mimic of tyrosine, in terms of binding to the active site of PTPs[1].
