Abstract
The lysU gene encoding lysyl-tRNA synthetase of Escherichia coli is normally silent at low temperatures and is expressed by certain metabolites and stimuli. A novel class of lysU-constitutive mutations were isolated by random insertion mutagenesis. These mutations nullified the hns gene encoding a histone-like protein, H-NS, and affected thermoregulation of lysU.Keywords
