In the meanwhile, a new trigonal … Porins are beta barrel proteins that cross a cellular membrane and act as a pore, through which molecules can diffuse. Unlike other membrane transport proteins, porins are large enough to allow passive diffusion, i.e., they act as channels that are specific to different types of molecules. They are present in the … See more Porins are composed of beta sheets (β sheets) made up of beta strands (β strands) which are linked together by beta turns on the cytoplasmic side and long loops of amino acids on the other. The β strands lie in an See more Porins are water-filled pores and channels found in the membranes of bacteria and eukaryotes. Porin-like channels have also been discovered in archaea. Note that the term "nucleoporin" refers to unrelated proteins that facilitate transport through nuclear pores in the See more The discovery of porins has been attributed to Hiroshi Nikaido, nicknamed "the porinologist."
