Welcome to OpenStudy! My name is Stephen, and I can help you with your problem (: 

ATP is used as a substrate in signal transduction pathways by kinases that phosphorylate proteins and lipids. The most common ATP-binding proteins, known as kinases, share a small number of common folds; the protein kinases, the largest kinase superfamily, all share common structural features specialized for ATP binding and phosphate transfer.

ATP in complexes with proteins, in general, requires the presence of a divalent cation, almost always magnesium, which binds to the ATP phosphate groups. The presence of magnesium greatly decreases the dissociation constant of ATP from its protein binding partner without affecting the ability of the enzyme to catalyze its reaction once the ATP has bound.The presence of magnesium ions can serve as a mechanism for kinase regulation

Atp releases energy and hydrolyzes, becomes adp to perform work
