How antifreeze proteins make ice crystals grow

Bacteria, plants, insects and fish use antifreeze proteins to protect themselves from the cold. The proteins block the growth of ice crystals. In a new study, a German-Israeli research team has confirmed that these proteins ...

Enzyme's unfrozen adventure: In crystallo protein thermodynamics

Enzymes—biocatalysts made of proteins—are hugely important molecules that catalyze the reactions and processes in living organisms. Ongoing work to understand their structures and reaction mechanisms is therefore vital ...

Researchers image atomic structure of important immune regulator

A new study by investigators from Brigham and Women's Hospital provides a biophysical and structural assessment of a critical immune regulating protein called human T-cell immunoglobulin and mucin domain containing protein-3 ...

Questioning conventional understanding of antifreeze proteins

Scientists have discovered that an ice-binding protein (fcIBP) from sea ice microalga does not fit in the conventional classification of ice-binding proteins, suggesting unknown mechanisms behind its antifreeze property. ...
