Figure 3.

Functional categorization of detected outer or inner envelope proteins. Shown are all proteins clustered by their known functions (Tables 3– 5). The proteins of each cluster are sorted by the localization in the inner (IE) or in the outer envelope (OE) fraction. Proteins with an unclear localization (ENV) are listed in a separated cluster. Also proteins with unknown function (Table 6) are listed in a separated cluster. Black boxes indicate proteins of category I and white boxes proteins of category III (Table 1). * Indicates not found in ENV but clearly localized to IE or OE known from literature. ^∧Indicates localized to IE or OE but only detected with one peptide.
