New research on life sciences from University of Utah summarized
July 8th, 2008
"The mechanosensitive channel of large conductance (MscL) belongs to a family of transmembrane channel proteins in bacteria and functions as a safety valve that relieves the turgor pressure produced by osmotic downshock. MscL gating can be triggered solely by stretching of the membrane," scientists in the United States report. "This work reports an effort to understand this mechanotransduction by means of molecular dynamics (MD) simulation on the MscL of mycobacterium tuberculosis embedded in a palmitoyloleoylphosphatidylethanolamine membrane. Equilibrium MD under zero membrane tension produced a more compact protein structure, as measured by its radii of gyration,...
