Defects in the oxidative phosphorylation (OXPHOS) system — the final biochemical pathway in the production of ATP — result in devastating, mainly multisystem diseases. The OXPHOS system is ...

For the first time, scientists have described a way for cells to add phosphate groups to proteins that doesn't involve an ATP donor. A group at Johns Hopkins University in Baltimore synthesized ...

Phosphorylation is the enzymatic process through which a phosphate group is added via an ester bond, generally by a kinase, to either a small molecule or a protein. Protein phosphorylation is ...

ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has ...
