FIG. 2.

Summary of R-domain and arm mutant structures. The top of the diagram shows the 58-aa sequence of the WT CNV CP R-domain along with the downstream 34-aa arm region (open box) and the beginning of the S-domain. Shaded regions in the R-domain correspond to previously identified sequences found to be important for particle accumulation (unpublished data). The C-terminal LRR is indicated above the R-domain sequence. R and arm region mutants are shown beneath. Sequences retained in each mutant are shown. The presence of a proline (P) or glycine (G) at aa position 85 in the arm region of the various mutants is indicated in the shaded box.
