Figure 4.

Comparison of the functional group breakdown of the Arabidopsis mitochondrial proteome (543) with the subset of proteins containing clear N-terminal mitochondrial targeting sequences (207) and the set of experimentally determined dual-mitochondrial and chloroplast targeted proteins (35).

Functional breakdown was obtained from SUBA. Subset with N-terminal sequences defined as those predicted to be mitochondrial by both Predotar and TargetP. Dual-targeted sets were defined predominantly by GFP-tagging and were all gained from published literature searches.
