Accommodation of elongation factors. a Superposition of Pol II–NCP structure with the mammalian paused elongation complex PEC (PDB code 6GML) provides the location of DSIF and NELF. b Superposition of the mammalian activated elongation complex EC* (PDB code 6GMH) provides the location of PAF1 complex (PAF) and SPT6
