Primer extension analysis to identify the transcription start site in the pVA891-ori plasmids. The primer extension reaction was performed with total RNA isolated from L. lactis containing plasmid pLP201 or pLP203 by using primer 6902prex. The primer extension products in both lanes are indicated by the arrow. The same primer was used for the sequencing reaction with pLP201 (lanes A, C, G, and T). Sizes (in nucleotides) are indicated on the left.
