protein kinase


protein kinase
Enzyme catalysing transfer of phosphate from ATP to hydroxyl side chains on proteins, causing changes in function. Most phosphate on proteins of animal cells is on serine residues, less on threonine, with a very small amount on tyrosineresidues. Tyrosine kinases phosphorylate proteins on tyrosine; serine/threonine kinases on serine or threonine.
