Fig. 3. H68-70 are flexible and invisible in the absence of the CTD of Rpf2.

Fig. 3

a Subunit interface view of density maps from the wild-type particles and the C4 class of rpf2Δ255-344 mutant particles. Densities for Rpf2, Rrs1, and H68-70 were colored using Color Zone in Chimera. b Atomic models for wild-type and C4 particles were fitted into density maps of wild-type and C4 particles, respectively. The C4 class of the rpf2Δ255-344 particles is missing densities for the CTD of Rpf2 and for H68-H71, except for the base of H68 and the H67-H71 linker. c Structural comparison of atomic models of the wild-type particle and mutant C4 particle in the stem base region of H68. One strand of the base of H68 in the C4 mutant is deflected up to 13 Å, as indicated by the displacement of C2195, and the H67-H71 linker is deflected up to 33 Å.
