==The X-ray crystal structure of a serpin from a thermophilic prokaryote==
-
Serpins utilize conformational change to inhibit target proteinases; the, price paid for this conformational flexibility is that many undergo, temperature-induced polymerization. Despite this thermolability, serpins, are present in the genomes of thermophilic prokaryotes, and here we, characterize the first such serpin, thermopin. Thermopin is a proteinase, inhibitor and, in comparison with human alpha(1)-antitrypsin, possesses, enhanced stability at 60 degrees C. The 1.5 A crystal structure reveals, novel structural features in regions implicated in serpin folding and, stability. Thermopin possesses a C-terminal "tail" that interacts with the, top of the A beta sheet and plays an important role in the, folding/unfolding of the molecule. These data provide evidence as to how, this unusual serpin has adapted to fold and function in a heated, environment.
