Application

Creatine amidinohydrolase is a clinically important enzyme used in the determination of creatinine in blood and urine.

Biochem/physiol Actions

Creatinase is a homodimer with subunit molecular weights of approximately 45 kDa. It catalyzes the hydrolysis of creatine, in the presence of H2O, to form urea and sarcosine.

Unit Definition

One unit will hydrolyze 1.0 μmole of creatine to urea and sarcosine per min at pH 7.5 at 37 °C.

I report on a 3-month-old infant with pulmonary atresia-intact ventricular septum and ventriculocoronary communication (VCC) who underwent percutaneous radiofrequency valvulotomy and valvuloplasty (RFVV). The patient's cardiac troponin-I, creatine kinase (CK), and myocardial fraction of (CK-MB) were elevated before RFVV and

A matrix made up of chitosan-SiO(2)-multiwall carbon nanotubes (CHIT-SiO(2)-MWCNTs) nanocomposite was fabricated to investigate the immobilization of creatine amidinohydrolase (CAH). CAH enzyme was covalently immobilized with the CHIT-SiO(2)-MWCNTs matrix using glutaraldehyde as a linker. The resulting CAH/CHIT-SiO(2)-MWCNTs biomatrix was characterized
