title: Analysis of the regulatory region of the lysC gene of Escherichia coli.
abstract: A lysC-lac'Z fusion plasmid was constructed to study the regulatory region of the lysC gene. Analysis by deletion mutations confirmed the existence of an alternative promoter, P2, located upstream of the previously identified promoter, P1. The transcription start site of promoter P2 was located 85 base pairs upstream the transcription start site of promoter P1. Both promoters are regulated by lysine.
