十七个独立分离的L-阿拉伯糖利用缺陷的突变体的鼠伤寒沙门氏菌LT 2的特点。四个互补组（araA，araB，araC和araD）被确定，相当于大肠杆菌中ara系统中的相同基因。4个基因的顺序为araD-araA-araB-araC-leu。发现两个转录单位：araBAD操纵子逆时针转录，araC基因顺时针转录。
Seventeen independently isolated L-arabinose utilization-deficient mutants of Salmonella typhimurium LT2 were characterized. Four complementation groups (araA, araB, araC, and araD) were identified and were equivalent to the same genes in the ara system in Escherichia coli. The order of the four genes was determined to be araD-araA-araB-araC-leu. Two transcription units were found: the araBAD operon was transcribed counterclockwise, and the araC gene was transcribed clockwise.
