Thalassiosira pseudonana

Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP.

Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.

The process of introducing a phosphate group on to a protein.

Catalysis of the reaction: ATP + a protein tyrosine = ADP + protein tyrosine phosphate.

Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.

NA

Catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein. This reaction requires the presence of cAMP.

An enzyme complex, composed of regulatory and catalytic subunits, that catalyzes protein phosphorylation. Inactive forms of the enzyme have two regulatory chains and two catalytic chains; activation by cAMP produces two active catalytic monomers and a regulatory dimer.

A protein complex that possesses protein serine/threonine kinase activity, and contains two catalytic alpha subunits and two regulatory beta subunits. Protein kinase CK2 complexes are found in nearly every subcellular compartment, and can phosphorylate many protein substrates in addition to casein.

Modulation of the activity of the enzyme cAMP-dependent protein kinase.
