A creatine kinase mutation, gene and use of the mutation. The mutation takes attached sequence 2 as a reference sequence, has at least one mutation selected from the 100th site, the 121st site and the 33rd site, takes creatine and adenosine triphosphate (ATP) as substrates and has a creatine kinase catalytic activity at least 50% higher than a parent. The creatine kinase mutation can be used to produce phosphocreatine. |
