 Kinase - Wikipedia, the free encyclopedia
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.
In some settings, the purpose of phosphorylation is to "activate" or "energize" a molecule, increasing its energy so it is able to participate in a subsequent reaction with a negative free-energy change.
The largest group of kinases are Protein kinases, which act on and modify the activity of specific proteins.

Adenylate kinase then converts AMP into ADP, which is the substrate for the light phase of photosynthesis.
Adenylate kinases have been identified from a wide variety of sources including 27 species of archaebacteria and eubacteria, 3 species of single cell eukaryotes, 2 species of yeast, 3 species of plants, 3 species of mammals, and birds.
The upstream receptor protein kinase gene is expressed from the same strand and is extremely close to the adenylate kinase gene.

 [No title]
This kinase was found to be a component of the multiprotein complex TAK/P-TEFb, which is an elongation factor for RNA polymerase II-directed transcription and functions by phosphorylating the C-terminal domain of the largest subunit of RNA polymerase II.
The kinase exists as a tetramer and is composed of an alpha, an alpha-prime, and two beta subunits.

 Rapid microbial testing with adenylate kinase technology
Adenylate kinase, an enzyme, is another element vital to all living organisms for the maintenance of energy pathways and metabolism.
AK technology utilises adenosine diphosphate (ADP) and microbial adenylate kinase to catalyse the production of ATP.4 Given the ability of enzymes to effect reactions without being depleted or changed in any way, it is possible to use microbial AK to generate almost unlimited amounts of its products.
