NF-kB is а trаnscriptiоn fаctоr that plays an impоrtant role in the inflammatory response. Under normal conditions, NF-kB is inactive because it is sequestered in the cytoplasm by interaction with the inhibitory protein I-kB. Activation of NF-kB requires the phosphorylation and subsequent degradation of I-kB. The I-kB kinase, IKK, is the enzyme responsible for this phosphorylation. IKK has two substrates, I-kB and ATP, and produces two products, I-kB -P and ADP. It has been found that IKK follows the reaction mechanism shown below. This mechanism is known as _______.
