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 _______.
