While insertion sequences (IS) in Escherichia coli transpose frequently to generate spontaneous insertion mutants, such mutations are rare in Salmonella typhimurium: the only documented insertion mutation is a hisD mutation caused by the Salmonella-specific IS element IS200. To obtain more examples
Salmonella typhimurium contains three electrophoretically separable enzyme activities that hydrolyze N-acetyl phenylalanine beta-naphthyl ester (NAPNE). One of these enzymes is an endoprotease, protease I. Mutations at a locus apeA near purE lead to loss of this enzyme. We have found that N-acetyl l
