Functionⁱ

Reversibly catalyzes the transfer of phosphate between ATP and various phosphogens (e.g. creatine phosphate). Creatine kinase isoenzymes play a central role in energy transduction in tissues with large, fluctuating energy demands, such as skeletal muscle, heart, brain and spermatozoa.

Catalytic activityⁱ

ATP + creatine = ADP + phosphocreatine.PROSITE-ProRule annotation
