ATP Biochem.|eɪtiːˈpiː|
Also A.T.P.
[Abbrev. of adenosine triphosphate.]
= adenosine triphosphate s.v. adenosine b.
1939[see adenosine b]. 1953Sci. Amer. Sept. 102/2 ATP delivers a phosphate to an amino acid, thereby creating an amino acid acylphosphate. 1956[see phosphoenolpyruvate s.v. phospho-]. 1964W. G. Smith Allergy & Tissue Metabolism viii. 86 The energy can be released from ATP by its reconversion to ADP and inorganic phosphate. 1976Ann. Rev. Microbiol. XXX. 6 We were able to isolate from the frog eggs several milligrams of ATP. 1983Oxf. Textbk. Med. II. xiii. 7/1 Energy in the form of ATP is used to maintain the integrity of cell structures, to fuel the pumps for maintenance of ionic gradients, and to bring about muscle shortening.
Hence ATPase |eɪtiːˈpiːeɪz|, an enzyme that hydrolyses ATP to adenosine diphosphate and inorganic phosphate.
1946Jrnl. Biol. Chem. CLXIII. 340 We conclude that the ATPase is contained only in a fraction of the myosin. 1975Sci. Amer. Dec. 35/1 We had been working with normal E. coli bacteria, and we decided..to try certain mutant strains that lack the enzyme ATPase. 1982J. F. Van Pilsum in T. M. Devlin Textbk. Biochem. xxi. 1007 The sliding filament model of muscle contraction involves the ATPase activity of the globular portion of the myosin molecule. 1984J. F. Lamb et al. Essent. Physiol. (ed. 2) i. 23 The current view of this pump is that it is a large phospholipid molecule in the surface membrane of the cell, which has ATPase (ability to split ATP) properties. |
