Fig. 5.

Stabilization of MceG protein by yrbEAB expression. M. smegmatis constitutively expressing a myc-tagged MceG protein was cotransformed with plasmids expressing the indicated genes. The amount of MceG in exponentially growing cultures of each strain was determined by Western blotting of whole cell extracts. Band intensities are plotted on a log scale. Data from two independent transformants of each strain are shown. “Vector” indicates the vector backbone for the yrbEAB-expressing plasmid.
