conformity to the preferred -- 35 and -- 10 sequences may not be sufficient to promote efficient utilization by b. subtilis rna polymerase , however , since three promoters ( veg , tms and e. coli tac ) that conform to these sequences and that are utilized efficiently by e. coli rna polymerase were used with highly varied efficiencies by b. subtilis rna polymerase .
