Abstract
The hisT gene, one of six genes in which mutation causes derepression of the histidine operon in Salmonella typhimurium , is shown to code for a protein that is not essential for the growth of the bacteria. This is indicated by the characterization of particular classes of mutations in the hisT gene: amber mutations, frame-shift mutations, and temperature-sensitive mutations that affect repression but not growth. In addition, the class of semilethal mutations was selected for but not found.
