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] 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. 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.
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.
