Electrotransformation data demonstrating that Clostridium pasteurianum restricts a 334 bp region within the ltrA gene sequence of pSY6catP. The 932 bp SacII-BstAPI region of pSY6catP (see Figure 1) is enlarged to better show relevant vector components. Point mutations within the ltrA coding sequence are depicted as vertical bands. Enlarged vector components are depicted to scale. Shaded box: Ll.ltrB intron; shaded arrow: ltrA; dashed line: Dcm recognition site; Pptb: ptb promoter (C. acetobutylicum); ND: not detected. Relevant restriction endonuclease recognition sites corresponding to AatII (A), BglII (B), EcoO109I (E), and SacII (S) are abbreviated using a single letter.
