Identification of thermophilic species by the amino acid compositions deduced from their genomes.

@article{citeulike:2288272, abstract = {The global amino acid compositions as deduced from the complete genomic sequences of six thermophilic archaea, two thermophilic bacteria, 17 mesophilic bacteria and two eukaryotic species were analysed by hierarchical clustering and principal components analysis.
