Abstract:
:The aecA and aecB loci map at 250 and 290 degrees, respectively, on the Bacillus subtilis chromosomal genetic map. The aecB locus has been proposed as the structural gene for aspartokinase II. From DNA sequence analyses and comparisons to the sequence of the aspartokinase II gene, it can be concluded that the structural gene for aspartokinase II is located close to sdh at 250 degrees and cannot be aecB. A detailed map over 7 kbp in the 250 degree region is presented.
