Detailed explanation-1: -Groups that are classified as phosphate acceptors include: alcohols, carboxy groups, nitrogenous groups, and phosphate groups. Further constituents of this subclass of transferases are various kinases. A prominent kinase is cyclin-dependent kinase (or CDK), which comprises a sub-family of protein kinases.

Detailed explanation-2: -Protein kinases and phosphatases are enzymes catalysing the transfer of phosphate between their substrates. A protein kinase catalyses the transfer of -phosphate from ATP (or GTP) to its protein substrates while a protein phosphatase catalyses the transfer of the phosphate from a phosphoprotein to a water molecule.

Detailed explanation-3: -A type of enzyme (a protein that speeds up chemical reactions in the body) that adds chemicals called phosphates to other molecules, such as sugars or proteins. This may cause other molecules in the cell to become either active or inactive. Kinases are a part of many cell processes.

Detailed explanation-4: -These enzymes, called transferases, move functional groups from one molecule to another. For example, alanine aminotransferase shuffles the alpha‐amino group between alanine and aspartate: Other transferases move phosphate groups between ATP and other compounds, sugar residues to form disaccharides, and so on.
