Acylation sites identified in viral proteins

The (proposed) transmembrane regions are underlined. See Figure 1 for the membrane topology of the respective category of proteins. Identified acylation sites are highlighted in red. Asterisks following a letter indicate that the fatty acid was identified as (mainly) stearic acid (C 18:0), whereas bold C's indicate the presence of predominantly palmitic acid (C 16:0) at the respective cysteine residue. Three dots (…) denote the presence of additional amino acids. For Env glycoproteins of HIV and SIV, the number of amino acids (aa) between the transmembrane region and acylation sites is specified. For abbreviation of viruses and proteins, see the glossary. Sequences were taken from viral zone (http://viralzone.expasy.org/).
