The precise physical locations of the oriC region and the region for type II DNA binding to the membrane on the Bacillus subtilis 168 chromosome were determined. The DNA regions were physically mapped by creating new restriction sites (NotI and SfiI) within these regions. The physical distance between oriC and the type II DNA-binding region was verified with the creation of a novel sequence cleaved by endonuclease I-SceI in each of the above regions. Complete removal of the defined type II membrane-binding region produced no noticeable phenotype.
确定了枯草芽孢杆菌168染色体上oriC区域以及II型DNA与膜结合区域的精确物理位置。通过在这些区域内创建新的限制酶切位点(NotI和SfiI)对DNA区域进行物理图谱绘制。通过在上述每个区域创建一个被I-SceI内切酶切割的新序列,验证了oriC与II型DNA结合区域之间的物理距离。完全去除确定的II型膜结合区域未产生明显的表型。
