Mutations in two unlinked genes are required to produce asparagine auxotrophy in Escherichia coli.
Escherichia coli K-12 has two genes, asnA+ and asnB+, either one of which is able to satisfy the need of cells for asparagine. In order for a strain to have an auxotrophic requirement for asparagine, both genes must be mutationally inactivated. We obtained mutants with Tn5 inserted in asnB. asnB was...
