Fig. 2From: Two conformations of DNA polymerase D-PCNA-DNA, an archaeal replisome complex, revealed by cryo-electron microscopyDocking of the TkoPCNA crystal structures on the 3D map of Form A. a The three subunits of the TkoPCNA are colored in different green. The interdomain connecting loops (IDCLs) are indicated by green arrows. b The same Form A map, in different threshold representation from a, to show the fit of alpha helices of PCNA. c Cross-sectional side view of Form A map. An atomic model of 25 bp B-DNA (blue) is docked into the map. The ribbon models of PolD are colored as in Fig. 1Back to article page
