Organisms respond to sudden increases in temperature by synthesizing a small set of
proteins called the heat-shock proteins (hsps)(See Figure 1). This heat-shock response has
been highly conserved throughout evolution, not only as a physiological phenomenon, but
also at the level of the individual proteins. Hsps comprise some of the most highly conserved
protein families known. The level of amino-acid identity between all prokaryotic and
eukaryotic hsp70 proteins, for example, approaches 50%(95). Hsp families often include …
