Influence of L-leucine and L-alanine on Lrp regulation of foo, coding for F1651, a Pap homologue.

Journal of bacteriology - 1 Dec 2004

Abstract excerpt

The foo operon encodes F165 1 fimbriae that belong to the P-regulatory family and are synthesized by septicemic Escherichia coli. Using an Lrp-deficient host and the lrp gene cloned under the arabinose pBAD promoter, we demonstrated that foo was transcribed proportionally to the amount of Lrp synthesized. L-leucine and L-alanine decreased drastically the steady-state transcription of foo and modified phase...
