Teg49 is a non-coding RNA present in the extended promoter region of the staphylococcal accessory regulator sarA. It was identified by RNA-seq and confirmed by Northern blot. It is modulated by sigB (sarA regulator[1]) and cshA (an ATP-dependant DEAD box RNA helicase[2]) and it most likely contributes to virulence of S. aureus by modulating SarA expression.[3]
