The ilv-leu operon is
WebWe used primer extension and mutational analysis to identify a promoter upstream of ilvB, the first gene in the ilv-leu operon of Bacillus subtilis. Between the promoter and ilvB, there is a 482-bp leader region which contains a sequence that resembles a factor-independent transcription terminator. WebTranscription start site of ilv-leu operon is indicated by +1 and an arrow, and translation start site is indicated by the initiation codon. The ribosome binding site (rbs) and the promoter region of ilv 25 are indicated as black and white squares. All the marked positions are indicated as the relative distance to transcription start site.
