摘要:
The synthesis of a new unnatural amino acid, N-alpha-N-epsilon-(ferrocene-1-acetyl)-L-lysine, was achieved by coupling a ferroceneacetic acid molecule onto the side chain amine of a lysine. The structure of the compound provides options for incorporation of the molecule into peptides or large proteins. In addition, N-alpha-N-epsilon-(ferrocene-1-acetyl)-L-lysine exhibits nuclease activity. It is expected that incorporation of this ferrocenyl amino acid into any nucleic acid-binding protein will endow the protein with nuclease capability. (C) 2008 Elsevier B. V. All rights reserved.
