WebThree separate strategies for managing the critical N-terminal cysteine residue have been developed: (i) incorporation of N (alpha)-9-fluorenylmethoxycarbonyl-S- (N-methyl-N-phenylcarbamoyl)sulfenylcysteine [Fmoc-Cys (Snm)-OH], allowing creation of an otherwise fully protected resin-bound intermediate with N-terminal free Cys; (ii) incorporation … WebThioester-containing proteins (TEP) are large secreted proteins playing central roles in the innate immune response [ 1, 2 ]. TEP are characterized by the presence of a unique intrachain β-cysteinyl-γ-glutamyl thioester bond (CGEQ) originally discovered in the human protease inhibitor, α-2-macroglobulin (A2M), and complement C3 and C4 [ 3 ].
