Sentence examples for mutant bacteria express from inspiring English sources

Collectively, these results suggest that the flagellar-deficient flgE mutant bacteria express lower levels of LPS on its outer membrane.

E. coli bacteria express two respiratory oxidases for oxygen reduction.

As controls, we compared double loss of function to single mutants grown on bacteria expressing gfp-directed dsRNA.

Binding of bacteria expressing mutant P66 proteins was normalized to binding of WT bacteria to allow incorporation of data from multiple experiments into the statistical analyses and figures, as raw OD values were not always identical in different experiments.

E40 bacteria expressing V98D,N99A mutant YadA with a severely reduced ability to bind collagen were found to be more resistant to killing, suggesting that collagen binding contributes significantly to sensitivity to NETs.

To determine if these insertions in urease's surface exposed loops altered its activity or stability we assayed enzymatic activity in bacteria expressing wild-type or mutant urease after exposure to acid (pH 3).

H. pylori expressing urease with insertions at four of eight sites tested retained urease activity, which in three cases was at least as stable as was wild-type urease at pH 3. Bacteria expressing one of these four mutant ureases, however, failed to colonise mice for even two weeks, and a second had reduced bacterial titres after longer term (3 to 6 months) colonisation.

To test this assumption we first optimized a method for extracting water-soluble as well as aggregated and water-insoluble CBS from bacteria expressing wild -ype and four mutant enzymes (for details, see the Methods section).
