%X We introduce a simplified protein model where the water degrees of freedom appear explicitly (although in an extremely simplified fashion). Using this model we are able to recover both the warm and the cold protein denaturation within a single framework, while addressing important issues about the structure of model proteins. %I Springer-Verlag %K Cold denaturation; hydrophobic forces; proteins %P 229-241 %T Cold and warm denaturation of proteins %V 27 %N 2/3 %L eprints1142 %A Guido Caldarelli %A Paolo De Los Rios %J Journal of Biological Physics %D 2001 %R 10.1023/A:1013145009949
