Genetic mapping of a mutant defective in D,L-alanine racemase in Bacillus subtilis 168.
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.
