| contents | At what cost? The impact of bacteriophage resistance on the growth kinetics and protein synthesis of Escherichia coli. Landor, Lotta A I Tjendra, Jesslyn Erstad, Karen Krabberød, Anders K Töpper, Joachim P Våge, Selina Escherichia coli Bacteriophages Protein Biosynthesis Mutation Escherichia coli Proteins Kinetics Glucose Cost of bacteriophage resistance (COR) is important in explaining processes of diversification and coexistence in microbial communities. COR can be expressed in different traits, and the lack of universally applicable methods to measure fitness trade-offs makes COR challenging to study. Due to its fundamental role in growth, we explored protein synthesis as a target for quantifying COR. In this study, the growth kinetics of three genome-sequenced strains of phage-resistant Escherichia coli, along with the phage-susceptible wild-type, were characterized over a range of glucose concentrations. Bioorthogonal non-canonical amino acid tagging (BONCAT) was used to track differences in protein synthetic activity between the wild-type and phage-resistant E. coli. Two of the resistant strains, with different levels of phage susceptibility, showed mucoid phenotypes corresponding with mutations in genes associated with the Rcs phosphorelay. These mucoid isolates, however, had reduced growth rates and potentially lower protein synthetic activity. Another resistant isolate with a different mutational profile maintained the same growth rate as the wild-type and showed increased BONCAT fluorescence, but its yield was lower. Together, these findings present different patterns of trade-offs resulting from the phage-induced mutations and demonstrate the potential applicability of BONCAT as a tool for measuring COR. |
