RNA polymerase was purified from five species of Bacillus, including Bacillus subtilis. Each polymerase had a subunit composition analogous to that reported for B. subtilis, i.e., beta beta '2 alpha sigma delta omega 1 omega 2. The delta subunits from the B. subtilis and Bacillus thuringiensis polymerases were interchangeable, as judged from their effects on promoter selection in the polymerase binding assay.

从包括枯草芽孢杆菌在内的五种芽孢杆菌中纯化出了RNA聚合酶。每种聚合酶的亚基组成与已报道的枯草芽孢杆菌的亚基组成相似，即ββ'2ασδε1ε2。从它们在聚合酶结合试验中对启动子选择的影响判断，枯草芽孢杆菌和苏云金芽孢杆菌聚合酶的δ亚基是可互换的。
