The coordination of primase function within the replisome is an essential but poorly understood feature of lagging strand synthesis. By using crystallography and small-angle X-ray scattering (SAXS), we show that functional elements of bacterial primase transition between two dominant conformations: an extended form that uncouples a regulatory domain from its associated RNA polymerase core and a compact state that sequesters the regulatory region from the site of primer synthesis ...
