Fig. 7From: SARS-CoV-2 accessory protein 7b forms homotetramers in detergentModels of 7b-TM homotetramer. A–B Two tetrameric models obtained by interaction of two disulfide-linked dimers (yellow). The dimers were obtained with Alpha-Fold, whereas the tetramer was embedded in a POPC membrane; C the pore diameter reaches zero in several parts along the channel for both models (lower panel)Back to article page
