Notes
LysR-family. leuO is upstream and divergent of the leuABCD operon. LeuO is required for recovery of a relA1 strain from starvation for brached-chain amino acids. In Salmonella, LeuO relieves leuABCD silencing mediated by an AT-rich silencer sequence between leuO and leuA. In Salmonella, LeuO expression is activated by an ilvHI-leuO-leuA promoter relay mechanism mediated by DNA supercoiling, possibly explaining the ppGpp-dependent increase in E. coli LeuO expression in stationary phase as an indirect effect of ppGpp stimulating the expression of Lrp, an ilvHI activator.[4]
