Protein Structure from Scientific Research

Comparison of the subunits of PEP (left) and cyanobacteria RNAP (right). The -CTDs are not resolved in reconstruction of cyanobacterial RNAP due to flexibility in the linker (dashed lines). By contrast, the -CTDs and the linker of 1are ordered in PEP. Details of the PEP 1subunit (inset) with residues of the linker indicated. See alsoFigure S4.
