In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion. [1] This process and its inverse, dephosphorylation , are common in biology . [ 2 ] Protein phosphorylation often activates (or deactivates) many enzymes .

2022年1月13日 · We can define phosphorylation as a biochemical process in which a phosphate molecule is added to some organic compound, such as glucose and adenosine diphosphate (ADP).

Phosphorylation, in chemistry, the addition of a phosphoryl group (PO32-) to an organic compound. The process by which much of the energy in foods is conserved and made available to the cell is called oxidative phosphorylation (see cellular respiration).

2024年8月13日 · Phosphorylation is the chemical addition of a phosphoryl group to an organic molecule. The removal of a phosphoryl group (PO3-) is called dephosphorylation. Enzymes (e.g., kinases, phosphotransferases) carry both phosphorylation and dephosphorylation.

Protein phosphorylation is a reversible post-translational modification of proteins in which an amino acid residue is phosphorylated by a protein kinase by the addition of a covalently bound phosphate group.

2022年4月13日 · Phosphorylation is a biochemical process through which a phosphate group (PO 4 3-) is transferred from one molecule to another, under the influence of a specialized group of enzymes, kinases. Here, a phosphate group is added via an ester bond.

Protein phosphorylation is the major molecular mechanism through which protein function is regulated in response to extracellular stimuli both inside and outside the nervous system.

Phosphorylation is the most common mechanism of regulating protein function and transmitting signals throughout the cell. While phosphorylation has been observed in bacterial proteins, it is considerably more pervasive in eukaryotic cells.

Protein phosphorylation is one of the most common and important post-translational modifications (PTMs) (1, 2). This reversible mechanism occurs through protein kinases and consists of the addition of a phosphate group (PO 4) to the polar group R of various amino acids.
