Promoters of Various Strength for Customized mRNA Synthesis

Promoters of Various Strength for Customized mRNA Synthesis 

Some of the native B. subtilis chromosomal genes have also strong constitutive promoters such as the promoter of the rpsD gene, the P43 promoter [137], the lepA promoter [123], and the first RNA polymerase binding site of the tandem promoter complex of the veg gene [138]. The strength of the ve I promoter is comparable with that of the SPOl promoters. Interestingly, the transcription initiated from P j and its native partner, the second veg promoter, collide with each other and produce much less mRNA [139].
