Monounsaturated Fatty Acids Are Substrates for Aldehyde Generation in Tellurite-Exposed Escherichia coli

Figure 5

Protein carbonylation in E. coli exposed to different toxicants. Cells carrying pBAD, pfabA, or pcfa were exposed to the indicated oxidative stress elicitors for 30 min in VB minimal media, and carbonyl groups were assessed using 2,4 DNPH as indicated in Section 2. Error bars represent SD (𝑛=5). Asterisks indicate significant difference, 𝑃<0.05.
