โฆ Synopsis
Protease-Catalyzed Peptide Synthesis from N-to C-Terminus: An Advantageous Strategy.
-A stepwise enzymatic peptide synthesis in the non-conventional N . fwdarw. C direction avoiding the risks of racemization is demonstrated for the model tetrapeptide H-Lys-Tyr-Arg-Ser-OH using the cysteine protease Clostripain. The tetrapeptide is obtained in 62% overall yield.
