Native Microorganism Creatine Amidinohydrolase

Cat No.
DIA-141
Description
Creatine Amidinohydrolase catalyzes the hydrolytic reaction converting creatine to sarcosine and urea. The enzyme is purified from a microorganism. The molecular weight of the enzyme is approximately 67,000. The enzyme is useful for the enzymatic assay of creatine and creatinine when coupled with other related enzymes. creatine + H2O → sarcosine + urea
