In recent years a growing interest has been addressed to cold-adapted microorganisms, because of their biotechnological applications.1,2 The knowledge of the structural and functional features that justify the unusual activity of psychrophilic enzymes at low temperature represents the main goal of many comparative analyses;3–6 indeed, this information is instrumental toward an exploitation of their biotechnological potential as suitable catalysts in future applications, like those in the dairy industry,7–8 in “cold washing” or in any situation where high activity at low temperature and an easy inactivation of added catalysts by moderate heating are required.
