Web17. okt 2014 · The crystal structure of bactericidal permeability-increasing protein (BPI), which is an LPS-binding protein, is similar to LBP . In humans, LBP and BPI are structurally similar with 45% sequence identity . Although these two proteins have similar structures, the biological roles of LBP and BPI are different. WebIon permeability in biological membranes is controlled through transmembrane proteins. In the case of passive transport, or in this case facilitated diffusion, of potassium ions, for example, transport is enabled by transmembrane proteins with a pore for potassium ions.
