A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to the tyrosine residues of specific proteins inside a cell. It functions as an "on" or "off" switch in many cellular functions. Tyrosine kinases belong to a larger class of enzymes known as protein kinases which also attach … See more Protein kinases are a group of enzymes that possess a catalytic subunit that transfers the gamma (terminal) phosphate from nucleoside triphosphates (often ATP) to one or more amino acid residues in a protein substrate … See more Kinase is a large family of enzymes that are responsible for catalyzing the transfer of a phosphoryl group from a nucleoside triphosphate donor, such as ATP, to an acceptor molecule. Tyrosine kinases catalyze the phosphorylation of tyrosine residues in … See more Protein tyrosine kinase proteins contain a Protein kinase domain, which consists of an N-terminal lobe comprising 5 beta sheet strands and an alpha helix called the C-helix, and a See more Tyrosine kinases are particularly important today because of their implications in the treatment of cancer.
