Comparison of codon usage between human and HIV-1. Codon usage data for human and HIV-1 were obtained from the codon usage database of Kazusa (http://www.kazusa.or.jp/codon/). Eight codons, i.e. UUA and CUA (leucine), AUA (isoleucine), GUA (valine), CAA (glutamine), AAU (asparagine), AGA (arginine) and GGA (glycine) were found to be present at levels > twofold in the HIV-1 genome compared to the human genome (represented by *). Tryptophan which has only one codon (i.e. UGG) is represented by #. An increase in UGG in HIV-1 simply means that tryptophan is more prevalent in HIV-1 than in human proteins
