Escherichia coli Lrp (leucine-responsive regulatory protein) does not directly regulate expression of the leu operon promoter.

Journal of bacteriology - 1 Oct 1999

Landgraf J R, Boxer J A, Calvo J M

Abstract excerpt

Studies by R. Lin et al. (J. Bacteriol. 174:1948-1955, 1992) suggested that the Escherichia coli leu operon might be a member of the Lrp regulon. Their results were obtained with a leucine auxotroph; in leucine prototrophs grown in a medium lacking leucine, there was little difference in leu operon expression between lrp(+) and lrp strains. Furthermore, when leuP-lacZ transcriptional fusions that lacked the leu...
