Abstract

A Bacillus subtilis mutant which carries a lesion in a gene specific to the synthesis of the dipeptide antibiotic bacilysin was isolated. A derivative strain in which transposon Tn917 had inserted near the bacilysin lesion was isolated and used as the donor in PBS-1 transduction mapping experiments. The bac-1 locus was mapped between the ctrA and sacA loci, near 90% on the standard B. subtilis 168 chromosome map.

摘要

分离出一株枯草芽孢杆菌突变体,该突变体在二肽抗生素杆菌溶素合成的一个特定基因中存在损伤。分离出一个转座子Tn917插入到杆菌溶素损伤附近的衍生菌株,并将其用作PBS-1转导定位实验的供体。bac-1位点被定位在ctrA和sacA位点之间,在标准枯草芽孢杆菌168染色体图谱上接近90%的位置。
