## Abstract Leucine is transported into E coli by two osmotic shock‐sensitive, high‐affinity systems (LIV‐I and leucine‐specific systems) and one membrane bound, low‐affinity system (LIV‐II). Expression of the high‐affinity transport systems is altered by mutations in __liv R__ and __1st R__, genes
Temperature-sensitive mutants that exhibit an altered haemolytic phenotype were isolated from Escherichia coli harbouring the plasmid pHly152. Complementation with recombinant plasmids carrying one of the four hly genes (C, A, B or D) allowed localization of the hly(ts) mutations. A ts mutation in h
