Genetic analysis of a d-alanine requiring mutant (dal) of Bacillus subtilis reveals that the gene that codes for d,l-alanine racemase is linked to purB. The order of genes in this region of the chromosome is purB, pig, tsi, dal. Thus there are at least two clusters of genes that regulate cell wall biosynthesis in B. subtilis.
对枯草芽孢杆菌的一个需要D-丙氨酸的突变体(dal)进行的遗传分析表明,编码D,L-丙氨酸消旋酶的基因与purB相连。染色体该区域的基因顺序是purB、pig、tsi、dal。因此,枯草芽孢杆菌中至少有两个调节细胞壁生物合成的基因簇。
