kinase

 [ki´nās]
1. a subclass of the transferases, comprising the enzymes that catalyze the transfer of a high-energy group from a donor (usually ATP) to an acceptor, and named, according to the acceptor, as creatine kinase, fructokinase, etc.
2. an enzyme that activates a zymogen, named, according to its source, such as enterokinase, streptokinase, etc.

ki·nase

(kī'nās),
1. Enzyme that catalyzes conversion of a proenzyme to an active one (for example, enteropeptidase [enterokinase]). Important in salvage and recycling of nucleotides. Some antiviral agents work by inactivating viral or tumor kinases
2. Suffix attached to some enzymes to indicate transformation.

kinase

/ki·nase/ (ki´nās)
1. a subclass of the transferases, comprising the enzymes that catalyze the transfer of a high-energy group from a donor (usually ATP) to an acceptor.
2. a suffix used in the names of some enzymes that convert an inactive or precursor form.

kinase

(kī′nās′, -nāz′, kĭn′ās′, -āz′)
n.
Any of various enzymes that catalyze the transfer of a phosphate group from a donor, such as ADP or ATP, to an acceptor protein. Kinases regulate many essential cellular processes.

kinase

[kī′nās]
Etymology: Gk, kinesis, motion; ase, enzyme
1 an enzyme that catalyzes the transfer of a phosphate group or another high-energy molecular group to an acceptor molecule. Each of these kinases is named for its receptor, such as acetate kinase, fructokinase, or hexokinase.
2 an enzyme that activates a preenzyme (zymogen). Each of these kinases is named for its source, such as bacterial kinase, enterokinase, fibrinokinase, insulin kinase, staphylokinase, streptokinase, streptokinase-streptodornase, or urokinase.

ki·nase

(kī'nās)
1. An enzyme catalyzing the conversion of a proenzyme to an active enzyme.
2. An enzyme catalyzing the transfer of phosphate groups to form triphosphates (e.g., adenosine triphosphate).

kinase

See TRANSFERASE.

kinase

an enzyme that catalyses the transfer of a phosphoryl group from ATP to another compound.

kinase

enzyme catalysing conversion of a proenzyme to an active enzyme; e.g. adenosine triphosphate (ATP) protein kinase (catalyses formation of ATP from adenosine diphosphate)

kinase

1. a subclass of the transferases, comprising the enzymes that catalyze the transfer of a high-energy group from a donor (usually ATP) to an acceptor, and named, according to the acceptor, as creatine kinase, fructokinase, etc.
2. an enzyme that activates a zymogen, and named, according to its source, as enterokinase, streptokinase, etc.

protein k's
cellular enzymes which utilize ATP to phosphorylate proteins, usually at a selected OH group of serine, threonine or tyrosine residue in the protein, so as to increase or decrease the activity of the protein.
protein kinase C
membrane bound protein kinase designated C because it requires Ca2+ and phosphatidyl serine for its activity. Activated by sn-1,2-diacylglycerol (DAG) produced from phosphatidyl inositol 4,5-bisphosphate. Phosphorylates target proteins such as the insulin receptor, β-adrenergic receptor, glucose transporter, HMG-CoA reductase, cytochrome P-450 and tyrosine hydroxylase.
