Evidence that the majority of leucine transfer ribonucleic acid is not involved in repression in Salmonella typhimurium.

M Freundlich, J Trela, W Peng.   

Abstract

Leucine transfer ribonucleic acid (tRNA) was almost fully charged, and the isoleucine-valine and leucine enzymes remained derepressed when trifluoroleucine was added to a leucine auxotroph. High levels of charged leucine tRNA and derepression were also found in a leucyl-tRNA synthetase mutant.
