RsgA a control point in 30S subunit maturation

Figure_1_RsgA2017_OverviewLópez-Alonso et al have described in Nucleic Acids Research our first high-resolution cryo-EM structure of the 30S-RsgA complex and reveal details of how RsgA may act as a control point to ascertain if the assembling 30S decoding site is properly folded and modified before triggering its own GTPase activity and allowing the 30S subunit to transition into the active pool of subunit .
