Protein

Creatine kinase B-type

Gene

CKB

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: -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 (By similarity).By similarity

Catalytic activityi

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