Collection of regulogs for ykoK (RF00380) RNA regulatory element

The ykoK RNA motif, or M-box, is a magnesium-sensing RNA structure that controls the expression of magnesium ion transport genes in Bacteria. The ykoK leader RNA motif was originally identified upstream of the ykoK (mgtE) gene in Bacillus subtilis and genes with related functions in other bacteria [15096624]. Examples of the conserved M-box RNA structure occur upstream of each of the three major families of Mg2+ transporters (CorA, MgtE and MgtA/MgtB) in various bacterial species [15096624]. The M-box RNAs control expression of downstream genes via regulated terminator formation, a mechanism commonly referred to as transcription attenuation. more
