Transverse tubules (T-tubules) play a significant role in muscle contraction. However, the underlying mechanism of their ...

Cells have a remarkable housekeeping system: proteins that are no longer needed, defective, or potentially harmful are labeled with a molecular "tag" and dismantled in the cellular recycling machinery ...

Enzyme mechanisms are the chemical transformations, and the steps within them, generated by enzymatic action on substrates. The mechanism of enzyme catalysis is similar in principle to other types of ...

A major goal of structural and functional genomics (or proteomics) is to deduce the structure and function of novel proteins by finding sequence homologies to biochemically well-characterized proteins ...

Encouraged by these results, Dudin, Dey, Guichard, and Hamel launched a close collaboration. Three years later, their work has produced near-encyclopedic insight into hundreds of protist species and ...
