Evolution and Diversity of Prokaryotic Small Heat Shock Proteins
To understand the evolutionary mechanisms that led to the diversification of the various types of heat shock proteins(Hsps) and their functioning in multichaperone networks is a great challenge (Feder and Hofmann 1999). Considerable information is already available on the evolution of the Hsp60 and Hsp70 families (e.g., Gupta 1995; Budin and Philippe 1998; Karlin and Brocchieri 1998; Macario et al. 1999; Archibald et al. 2000; Brocchieri and Karlin 2000). Relatively less is known about the early evolution of the small heat shock proteins (sHsps), which are considerably more divergent in structure and function than the Hsp60s and Hsp70s.
