It is important to note, however, that fully folded proteins are not frozen into shape. Rather, the atoms within these proteins remain capable of making small movements. Even though proteins are ...

For example, proteases break down proteins, and dehydrogenases oxidize a substrate by removing hydrogen atoms. As a general rule, the "-ase" suffix identifies a protein as an enzyme, whereas the ...

Not having a complete accounting of the locations of a protein's hydrogen atoms is a conundrum with implications beyond the ...

According to the results, a calcium cation—a positively charged calcium ion—is located at a distance of less than 0.7 nanometers from the iron atoms the protein uses to store electrons.

Researchers have found that a chemical reaction links air pollution and Alzheimer's; blocking this reaction could be a ...
