Readily Adapts Membrane Phospholipid Composition to Environmental and Genetic Perturbation.

Front Microbiol 2021 21;12:616045. Epub 2021 May 21.

Department of Microbiology, University of Tennessee, Knoxville, Knoxville, TN, United States.

The bacterial lipid membrane, consisting both of fatty acid (acyl) tails and polar head groups, responds to changing conditions through alteration of either the acyl tails and/or head groups. This plasticity is critical for cell survival as it allows maintenance of both the protective nature of the membrane as well as functioning membrane protein complexes. Bacteria that live in fatty-acid rich environments, such as those found in the human host, can exploit host fatty acids to synthesize their own membranes, in turn, altering their physiology.
