Genetic studies with strain hisBH22 of Salmonella typhimurium indicate it contains a deletion within the histidine operon involving part of the hisH gene and all of the hisB gene, but not extending into the adjacent hisC gene which is adjacent to hisB. However, the specific activity of the hisC product, imidazolylacetolphosphate aminotransferase (EC, in this strain is only 10 to 15%
