Figure 1. skp deletion has no effect on the OM proteome.
Two-dimensional logarithmic plot for the mean SC values of the identified lipoproteins and β-barrel proteins. Spots on the diagonal and between the two dotted lines correspond to proteins that are not significantly affected by the loss of Skp (they differ in their SC values by a factor of less than 2). Closed circles (●) correspond to β-barrel proteins and closed triangles (▴) to lipoproteins. Only one spot corresponding to the LptE lipoprotein (above the upper dotted line) is decreased by more than twofold in the skp strain (NR745).
