transduction mapping of the ask operon , inactivated by recombinational insertion of a cat marker , indicates a chromosomal location ( about 253 degrees ) between leua and arog . ask is thus remote from aecb , eliminating aecb as a possible locus for the structural gene of aspartokinase ii , but close to aeca and uvrb .
