Cysteine, even in low concentrations, induces transient amino acid starvation in Escherichia coli

M A Sørensen et al. J Bacteriol. 1991 Aug.

Abstract

Cysteine, in concentrations down to 0.04 micrograms/ml, induces transient amino acid starvation in Escherichia coli growing in minimal medium. The duration depends on the concentration and is 5 min at 2 micrograms of cysteine per ml. At low cysteine concentrations, threonine and isoleucine almost completely abolish the starvation.
