FIG. 6.

Incorporation of radioactivity from ¹⁴C-labeled glucose into the acid-insoluble cellular fractions of L. pneumophila strains. Cells of gene-disrupted mutants (A) and various partial heterozygotes (B) were incubated for 24 h under the conditions described in Materials and Methods. The matrix below each graph shows the presence (+) or absence (−) of the relevant enzymes in each strain. In panel B, pMMB207 represents the vector used to construct the heterozygotes. The means and standard deviations of at least three independent determinations are shown.
