[Answer] A protein kinase activating many other protein kinases is an example of _____.

Answer: amplification
A protein kinase activating many other protein kinases is an example of _____.
A protein kinase is a kinase which selectively modifies other proteins by covalently adding phosphates to them (phosphorylation) as opposed to kinases which modify lipids carbohydrates or other molecules. Phosphorylation usually results in a functional change of the target protein (substrate) by changing enzyme activity cellular location or association with other proteins.
The human genome contains about 500 protein kinase genes and they constitute about 2% of all human genes. There are two main types of protein kinase the great majority are serine/threonine kinases which phosphorylate the hydroxyl groups of serines and threonines in their targets and the other are tyrosine kinases although additional types exist. Protein ki…
The human genome contains about 500 protein kinase genes and they constitute about 2% of all human genes. There are two main types of protein kinase the great majority are serine/threonine kinases which phosphorylate the hydroxyl groups of serines and threonines in their targets and the other are tyrosine kinases although additional types exist. Protein kinases are also found in bacteria and plants. Up to 30% of all human proteins may be modified by kinase activity and kinases are known to regulate the majority of cellular pathways especially those involved in signal transduction.
Protein kinase A more precisely known as adenosine 3′ 5′-monophosphate (cyclic AMP)-dependent protein kinase abbreviated to PKA was discovered by chemists Edmond H. Fischer and Edwin G. Krebs in 1968. They won the Nobel Prize in Physiology or Medicine in 1992 for their work on phosphorylation and dephosphorylation and how it relates to PKA activity. PKA is one of the most widely researched protein kinases in part because of its uniqueness; ou…
