title: IS30 activation of an smp'-lacZ gene fusion in Escherichia coli.
abstract: The Escherichia coli serB gene is divergently transcribed from the gene. Six independently isolated IS30 insertions within the 5' end of the serB structural gene resulted in increased expression of an smp'-lacZ gene fusion. DNA sequence analysis of two of the insertions suggests that a promoter was created upon IS30 insertion.
