Any of a group of enzymes that transfer phosphate groups from high-energy donor molecules, such as ATP, to specific target molecules (substrates), in a process termed phosphorylation.
(enzyme) Any of several enzymes that hydrolyze phosphate esters, and are important in the metabolism of carbohydrates, nucleotides and phospholipids, and in the formation of bone.
One of a class of enzymes that catalyze transfer of a phosphate group from ATP to another molecule; it is a type of phosphorylase.
any of a group of enzymes that act as a catalyst in the hydrolysis of organic phosphates
an enzyme that catalyzes the conversion of a proenzyme to an active enzyme
In biochemistry, a phosphatase is an enzyme that uses water to cleave a phosphoric acid monoester into a phosphate ion and an alcohol. Because a phosphatase enzyme catalyzes the hydrolysis of its substrate, it is a subcategory of hydrolases.
In biochemistry, a kinase 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 substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group.
