Phosphorylation usually results in a functional change of the target protein (substrate) by changing … Visa mer The chemical activity of a protein kinase involves removing a phosphate group from ATP and covalently attaching it to one of three amino acids that have a free hydroxyl group. Most kinases act on both serine and threonine, … Visa mer Eukaryotic protein kinases are enzymes that belong to a very extensive family of proteins that share a conserved catalytic core. The structures of over 280 human protein kinases have … Visa mer Tyrosine-specific protein kinases (EC 2.7.10.1 and EC 2.7.10.2) phosphorylate tyrosine amino acid residues, and like serine/threonine-specific kinases are used in Visa mer Histidine kinases are structurally distinct from most other protein kinases and are found mostly in prokaryotes as part of two-component signal transduction mechanisms. A phosphate group from ATP is first added to a histidine residue within the kinase, … Visa mer Serine/threonine protein kinases (EC 2.7.11.1) phosphorylate the OH group of serine or threonine (which have similar side chains). Activity of these protein kinases can be regulated by specific events (e.g., DNA damage), as well as numerous chemical signals, … Visa mer Some kinases have dual-specificity kinase activities. For example, MEK (MAPKK), which is involved in the MAP kinase cascade, is a both a … Visa mer Deregulated kinase activity is a frequent cause of disease, in particular cancer, wherein kinases regulate many aspects that control cell growth, movement and death.
