Distribution of potential membrane-associated palmitoylated cysteine residues in coronavirus nonstructural proteins 3, 4 and 6. Diagrams show relative amino acid length with predicted hydrophobic domains (blue), internal transmembrane sequences (yellow), and consensus sites of cysteine palmitoylation (red). Coronavirus nonstructural protein sequences were obtained from GenBank accession IDs listed in Figure 1.
