What is "kinase"

kinase \ki"nase\ (k[imac]"n[=a]s), n. (Biochemistry) One of a class of enzymes that catalyze transfer of a phosphate group from ATP to another molecule; it is a type of phosphorylase.

1902, from Greek kinein "to move" (see cite) + chemical suffix -ase.

n. (context enzyme organic compound English) Any of a group of enzymes that transfers phosphate groups from high-energy donor molecules, such as ATP, to specific target molecules (substrates), in a process termed phosphorylation.

n. an enzyme that catalyzes the conversion of a proenzyme to an active enzyme

In enzymology, a [acetyl-CoA carboxylase] kinase is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ATP and acetyl-CoA carboxylase, whereas its two products are ADP and acetyl-CoA carboxylase phosphate.

This enzyme belongs to the family of transferases, specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins ( protein-serine/threonine kinases). The systematic name of this enzyme class is ATP:[acetyl-CoA carboxylase] phosphotransferase. Other names in common use include acetyl coenzyme A carboxylase kinase (phosphorylating), acetyl-CoA carboxylase bound kinase, acetyl-CoA carboxylase kinase, acetyl-CoA carboxylase kinase (cAMP-independent), acetyl-CoA carboxylase kinase 2, acetyl-CoA carboxylase kinase-2, acetyl-CoA carboxylase kinase-3 (AMP-activated), acetyl-coenzyme A carboxylase kinase, ACK2, ACK3, AMPK, I-peptide kinase, and STK5.

In enzymology, a [tyrosine 3-monooxygenase] kinase is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ATP and tyrosine 3-monooxygenase, whereas its two products are ADP and phospho-[tyrosine-3-monooxygenase].

This enzyme belongs to the family of transferases, specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins ( protein-serine/threonine kinases). The systematic name of this enzyme class is ATP:[tyrosine-3-monoxygenase] phosphotransferase. Other names in common use include pheochromocytoma tyrosine hydroxylase-associated kinase, STK4, and tyrosine 3-monooxygenase kinase (phosphorylating). This enzyme participates in MAPK signaling pathway and non-small cell lung cancer.

(Pyruvate, phosphate dikinase) kinase (, PPDK regulatory protein, pyruvate, phosphate dikinase regulatory protein, bifunctional dikinase regulatory protein) is an enzyme with systematic name ADP:(pyruvate, phosphate dikinase) phosphotransferase. This enzyme catalyses the following chemical reaction

This enzyme is isolated from the plants Zea mays ( maize) and arabidopsis.

(Pyruvate, water dikinase) kinase (, PSRP, PEPS kinase) is an enzyme with systematic name ADP:(pyruvate, water dikinase) phosphotransferase. This enzyme catalyses the following chemical reaction

The enzyme from the bacterium Escherichia coli is bifunctional.
