Protein

Creatine kinase U-type, mitochondrial

Gene

CKMT1

Organism
Gallus gallus (Chicken)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

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
