Synthesis of N-terminally linked protein dimers and trimers by a combined native chemical ligation-CuAAC click chemistry strategy.
Org Lett. 2009; (18): 4144-7
A novel method for the synthesis of N-terminally linked protein multimers is reported. Azide and alkyne thioesters were synthesized for the N-terminal modification of expressed proteins using native chemical ligation (NCL). Proteins modified by these moieties can be joined together to form homodimers and homotrimers via Cu(I)-catalyzed azide-alkyne [3 + 2] cycloaddition (CuAAC) click chemistry. The orthogonal nature of this reaction allows the production of protein heteromultimers, and this is demonstrated by synthesis of a protein heterodimer.
