Hydrophilic and hydrophobic molecules tend to avoid each other. But phosphoglycosyl transferases, enzymes that reside on bacterial cell membranes, can bring these odd couples together and catalyze ...

Annotations of enzyme function provide critical starting points for generating and testing biological hypotheses, but the quality of functional annotations is hindered by uncertain assignments for ...

Biological cells invest much of their resources into the production of enzymes, which catalyze the conversion of substrates into products. An international team of bioinformaticians and biophysicists ...

An unnatural amino acid has given researchers a switch to turn on a specific enzyme with light. This tool will allow scientists to determine the timing of cellular signaling and identify which parts ...

An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced ...
