Abstract
Using the method of protein reconstitution into planar bilayer lipid membranes, the electrophysiological properties of a novel porin channel from the marine bacterium Marinomonas primoryensis (MpOmp) were characterized. The main characteristics were determined: the conductivity value of the single MpOmp channel, its selectivity, and the values of the critical closing potential in various media (neutral, weakly acidic, alkaline). Using an in silico approach, the geometric characteristics of the MpOmp pore and the distribution of charges at the mouth and inside the porin channel were predicted.
期刊介绍：
Biochemistry (Moscow), Supplement Series A: Membrane and Cell Biology is an international peer reviewed journal that publishes original articles on physical, chemical, and molecular mechanisms that underlie basic properties of biological membranes and mediate membrane-related cellular functions. The primary topics of the journal are membrane structure, mechanisms of membrane transport, bioenergetics and photobiology, intracellular signaling as well as membrane aspects of cell biology, immunology, and medicine. The journal is multidisciplinary and gives preference to those articles that employ a variety of experimental approaches, basically in biophysics but also in biochemistry, cytology, and molecular biology. The journal publishes articles that strive for unveiling membrane and cellular functions through innovative theoretical models and computer simulations.
