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.

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.

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).
