Partial characterization of a lysU mutant of Escherichia coli K-12.

Journal of bacteriology - 1 Mar 1991

Hassani M, Saluta M V, Bennett G N, Hirshfield I N

Abstract excerpt

The Escherichia coli K-12 strain GNB10181 shows no inducible lysyl-tRNA synthetase (LysRS) activity. Two-dimensional gel electrophoretic analysis of the polypeptides synthesized by this strain indicates that the normal lysU gene product, LysU, is absent. When both GNB10181 and its parent, MC4100,...
