Davies et al. reported that apart from the non-ATP mimetic inhibitors rapamycin and PD184352, even the most selective kinase inhibitors affected at least one additional protein kinase 27.

ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc.

ADP is the universal product of kinase and ATPase activity ... total adenosine concentration (ATP plus ADP) is kept constant for each sample while the percentage of ADP in each sample is changed ...

The Transcreener ADP 2 Assay uses a highly selective antibody and far-red fluorescent tracer to directly detect ADP produced by any ADP-producing enzyme (i.e. kinases, ATPases, helicases ...

Energy is released from ATP when the end phosphate is removed. Once ATP has released energy, it becomes ADP (adenosine diphosphate), which is a low energy molecule. ADP can be recharged back into ...
