Detailed explanation-1: -In biochemistry, a kinase (/ˈkaɪneɪs, ˈkɪneɪs, -eɪz/) is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the high-energy ATP molecule donates a phosphate group to the substrate molecule.

Detailed explanation-2: -Protein kinases are enzymes that catalyze the transfer of the -phosphate of ATP to the protein substrates, thus altering their functions.

Detailed explanation-3: -Protein kinases are enzymes that transfer a phosphate group from a molecule of ATP onto a protein or other substrate. This activity, known as ‘phosphorylation’, is important for a wide range of cellular processes.

Detailed explanation-4: -Protein kinases transfer a phosphoryl group from ATP onto target proteins and play a critical role in signal transduction and other cellular processes.
