This YdaO/YuaA leader is a conserved RNA structure found upstream of the ydaO and yuaA genes in Bacillus subtilis and related genes in other bacteria. The ydaO/yuaA element is thought to act as a genetic "off" switch for the ydaO and yuaA genes in its native state. It is believed that the element may be triggered during osmotic shock leading to activation of ydaO, a predicted amino acid transporter gene, and members of the yuaA-yubG operon which code for KtrA and KtrB K+ transporters.[1]
