One of a class of enzymes that catalyze transfer of a phosphate group from ATP to another molecule; it is a type of phosphorylase.
(kye´ nase) • An enzyme that transfers a phosphate group from ATP to another molecule. Protein kinases transfer phosphate from ATP to specific proteins, playing important roles in cell regulation.
An enzyme that catalyzes the transfer of phosphate groups from a high-energy phosphate-containing molecule (as ATP or ADP) to a substrate.
An enzyme that catalyses the transfer of the terminal Î³-phosphoryl group of ATP to an acceptor molecule, with the formation of ADP and the phosphorylated acceptor. Protein kinases are enzymes that transfer phosphoryl groups in this way to proteins, thus phosphorylating them at specific sites and often changing their activity as a result.
Enzyme family catalizing phosphorylation, i.e., addition of a phosphate group to its substrate.
an enzyme that catalyzes the conversion of a pro-enzyme to an active enzyme
an agent that phosphorylates specific target proteins
an enzyme that converts a protein into an enzyme
an enzyme that transfers a phosphate group from ATP, GTP, ADP, etc, to an enzyme, thereby activating the enzyme
an enzyme that transfers a phosphate group - usually from the g -phosphate from ATP - to a substrate molecule
an enzyme which puts a phosphate on a protein and a phosphatase is an enzyme which removes a phosphate from a protein
a type of enzyme that transfers phosphate groups from ATP to a specified substrate or target
(Kye' nase) - An enzyme that is important in regulating cell functions
KI-nase A type of enzyme that activates other proteins by adding a phosphate. 177
A protein that may act as part of a pathway of signals within a cell to communicate a change in behavior. For instance, some kinases are responsible for telling cells to grow.
An enzyme that adds phosphate groups to proteins.
A type of enzyme that transfers a phosphate group onto another molecule. Page Top
An enzyme that can transfer a phosphate from a high energy phosphate such as ATP, to an organic molecule.
An organic substance (enzyme) which activates other substances to develop into chemical ferments or enzymes.
Most second messengers act by switching on a protein kinase that in turn regulates the activity of other proteins by covalently tagging them with phosphates at specific amino-acid residues. Kinase signalling is normally terminated by a protein phosphatase, that snips off the phosphate groups. In tubules, CAP2b stimulated cGMP signalling is mediated by cGMP-dependent protein kinases.
Enzyme (e.g., a protein kinase) that catalyzes a phosphate-group transfer.
An enzyme that modulates the activity of other proteins through the addition of phosphate groups
An enzyme that transfers the terminal () phosphate group from ATP to a substrate. Protein kinases, which phosphorylate specific serine, threonine, or tyrosine residues in target proteins, play a critical role in regulating the activity of many cellular proteins. See also phosphatases.
A kinase is in general an enzyme that catalyses the transfer of a phosphate group from ATP to something else. In molecular biology, it has acquired the more specific verbal usage for the transfer onto DNA of a radiolabelled phosphate group. This would be done in order to use the resultant "hot" DNA as a probe.
molecule that phosphorylates, or adds a phosphate group onto, other molecules in the cell in order to turn them on or off. Often used in signaling cascades that tell the cell to carry out certain functions.
In biochemistry, a kinase is a type of enzyme that transfers phosphate groups from high-energy donor molecules, such as ATP, to specific target molecules (substrates); the process is termed phosphorylation. (An enzyme that removes phosphate groups from targets is known as a phosphatase.)
