Valyl-Transfer RNA: Role in Repression of the Isoleucine-Valine Enzymes in Escherichia coli.
alpha-Aminobutyric acid is activated but not transferred to valine-specific transfer RNA and is unable to repress the isoleucine-valine enzymes in Escherichia coli strain W. alpha-Amino-beta-chlorobutyric acid is activated and transferred to valine-specific transfer RNA and completely replaces valine in repression.
