Figure 7From: Mutagenesis of the transmembrane domain of the SARS coronavirus spike glycoprotein: refinement of the requirements for SARS coronavirus cell entryProposed model of membrane fusion, mediated by SARS S. The model predicts the lateral flexibility of the TMD and the adjacent aromatic and cysteine rich domains to accommodate the necessary intermediates during membrane fusion. Blue, aromatic domain; yellow, hydrophobic core; pink, cysteine rich domain, green triangles, cholesterol.Back to article page
