ATP supply in a muscle is sufficient for only 5- 6 seconds of vigorous activity. There are several ATP regeneration systems that each consist of an enzyme and a phosphate donor, for example acetate kinase/acetyl phosphate (AcK/AcP), pyruvate kinase/phosphoenolpyruvate We compared the abilities of several ATP regeneration systems to support the production of soluble proteins in a cell-free synthesis system. 0000002644 00000 n

The relative merits of various routes to ATP regeneration involving chemical synthesis, whole cells or organelles, or cell free enzymes are evaluated.
The regeneration of ATP from AMP can be achieved by including adenylate kinase (AdK), while ATP regeneration from adenosine requires inclusion of both adenosine kinase and AdK in the above regenration systems (7, 11). 0000001728 00000 n

An ATP regeneration system is a coupled enzymatic reaction that constantly produces ATP from ADP and a secondary phosphate donor. While changes in the ATP level in the reaction mixture were variable depending on the ATP regeneration system employed, the yields and solubilities of synthesized proteins did not always correlate with the ATP level.

After this the body must generate ATP. ATP structure, ATP hydrolysis to ADP, and reaction coupling. Although regeneration systems for ATP starting from adenosine‐5′‐diphosphate are available, certain limitations exist for both in vitro and in vivo applications requiring ATP regeneration from adenosine‐5′‐monophosphate, or adenosine. 0000004959 00000 n
