What is L-4,4'-BIPHENYLALANINE?

Description

4-Biphenylyl-L-alanine (BipA) is a synthetic amino acid that was prepared to put a?“leash” on genetically modified?Escherichia coli.?It replaces phenylalanine in the codon of unmodified?E. coli. Additional phenylalanine derivatives have been made for the same purpose.
G. M. Church at Harvard Medical School and F. J. Isaacs at Yale University are using?E. coli?as a model to explore ways to prevent genetically modified organisms (GMOs) from reproducing in the environment. Tagging a GMO with a non-natural amino acid such as BipA allows it to reproduce in the laboratory but not in nature. If this strategy is successful, the next step would be to extend it to commercial GMOs such as crop plants.

The Uses of L-4,4'-BIPHENYLALANINE

L-4,4''-Biphenylalanine is a useful reagent in the preparation of other biologically active small molecules.
