Crystal structure of the heterotrimeric primase PriSLX from S. solfataricus. a Two views of the PriSLX structure. The three subunits are drawn as ribbons, colored blue (PriS), light blue (PriL) and purple (PriX). The position and extent of the PriL-CTD is highlighted by a dashed oval. The N- and C-terminal residues included in the crystallographic model are labeled with N and C, respectively. The known location of the PriS active site is indicated by a star. b View of the PriSLX structure that highlights the mode of PriX binding to the PriSL subunits. PriX is shown as a purple ribbon, as in panel A, whereas the PriS and PriL subunits are drawn as a solvent-accessible gray molecular surface. The interface regions of PriS and PriL that are within 5 Å of PriX are colored red
