Cold Adaptation of Triosephosphate Isomerase
Biochemistry, 2017The main problem for enzymes from psychrophilic species, which need to work near the freezing point of liquid water, is the exponential decay of reaction rates as the temperature is decreased. Cold-adapted enzymes have solved this problem by shifting the activation enthalpy-entropy balance for the catalyzed reaction compared to those of their ...

Cold adaptation and the human face
American Journal of Physical Anthropology, 1970AbstractA framework is suggested within which the evolutionary biology of the human head and face can be explored; it includes several channels of natural and behavioral selection as well as modes of “plasticity” change.One aspect of the model is then examined by means of physiological and anthropometric experimentation.

Cold-Adapted and Mesophilic Brachyurins
Biological Chemistry, 2002Two different types of brachyurins, termed I and II, have been described in the literature. Within type I there are two subtypes, Ia and Ib. The prototype for the type I brachyurins is Fiddler crab collagenase I. Its cold-adapted analogue from Antarctic krill, termed euphaulysin, shares many of its characteristics.

Thermal adaptation comprises the physiological and morphological changes which reduce the strains of stressful environments. Changes occurring within the lifetime of an organism are termed phenotypic, in contrast to genetically fixed conditions of a species [503]. Phenotypic adaptations enlarge the capacity of existing effector mechanisms, typically as
