Engineered protein crystals make cells magnetic

If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside ...

New sample holder for protein crystallography

Proteins are huge molecules that often have complex three-dimensional structure and morphology that can include side chains, folds, and twists. This three-dimensional shape is often the determining factor of their function ...

New structure for human flu virus protein

Researchers from Oxford University have worked out the molecular structure of a protein that is vital for survival of the flu virus. Recently published in Nature, they used several different techniques to look at the arrangement ...

Designer proteins form wires and lattices on mineral surface

The goal of the research, published July 11 in the journal Nature, was to engineer artificial proteins to self-assemble on a crystal surface by creating an exact match between the pattern of amino acids in the protein and ...

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 ...
