This selenocysteine-derived building-block is used in NCL/deselenization technique. NCL is performed at selenocysteine followed by a selective deselenization reaction, which converts the Sec at the ligation site into Ala in the presence of unprotected Cys residues. Sez is deprotected into Sec by treatment with MeONH2 at pH 4. The deselenization reaction is done using TCEP in the presence of DTT. Sez can also be deprotected using Cu(II) salts. Fmoc-deprotection and Sez-opening can be done in one pot.
