According to deletion analysis, the region upstream from nucleotide 38 is not essential for transcription of BcLFI. A 23 bp region in the promoter, from nucleotide 38 to 16, was identified as necessary for regulating the expression of BcLFI, i.e. the promoter activity is activated by 12-O-tetradecanoylphorbol 13-acetate but is repressed by phosphonoacetic acid. The results presented also demonstrate that the oriLyt sequence in cis is essential for enhancing the expression of BcLF1. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-79-8-2003
