Antibacterial lysine analogs that target lysine riboswitches

Kenneth F Blount , Joy Xin Wang , Jinsoo Lim , Narasimhan Sudarsan & Ronald R Breaker

Lysine riboswitches are bacterial RNA structures that sense the concentration of lysine and regulate the expression of lysine biosynthesis and transport genes. Members of this riboswitch class are found in the 5|[prime]| untranslated region of messenger RNAs, where they form highly selective receptors for lysine.
