From: Evolutionary connection between the catalytic subunits of DNA-dependent RNA polymerases and eukaryotic RNA-dependent RNA polymerases and the origin of RNA polymerases

Figure 4

Structure of the catalytic cleft of DDRP formed by interacting DPBB domains of the β and β' subunits. The metal-coordinating DbDGD motif of the β' subunit and the functionally important lysines projecting into the catalytic cleft of the β subunit are shown in ball and stick representation. The two double psi-barrels are juxtaposed in an asymmetric head to tail configuration.
