Phenylalanine Increases Membrane Permeability [PDF]
Journal of the American Chemical Society, 2017 Abstract Biological membranes are a crucial aspect of living systems, controlling the organization and distribution of different chemical components. Control of membrane permeability is especially important for processes such as electron transport in metabolism and signal propagation in nerve cells.

CO2 permeability of the rat erythrocyte membrane and its inhibition
Journal of Enzyme Inhibition and Medicinal Chemistry, 2021 We have studied the CO2 permeability of the erythrocyte membrane of the rat using a mass spectrometric method that employs 18 O-labelled CO2. The method yields, in addition, the intraerythrocytic carbonic anhydrase activity and the membrane HCO3 ...

Alpha-toxin induces programmed cell death of human T cells, B cells, and monocytes during USA300 infection. [PDF]
PLoS ONE, 2012 This investigation examines the influence of alpha-toxin (Hla) during USA300 infection of human leukocytes. Survival of an USA300 isogenic deletion mutant of hla (USA300Δhla) in human blood was comparable to the parental wild-type strain and ...
