beta barrel

A protein structural motif consisting of antiparallel beta strands that form a hydrophobic protein core with a large beta-sheet that twists and coils, resulting in a closed structure in which the first strand is hydrogen bonded to the last. Beta barrels are found in porins and transmembrane proteins and encoded by up to 3% of gram-negative bacterial genes.
