Descriptions

Application

Creatinine Deiminase microbial has been used:to immobilize aminosilylated glass beads based biosensor for ammonia/ammonium and creatinine detection in urinein creating creatinine-sensing membrane for biophysical studiesto investigate the bioelectronic tongue for the simultaneous determination of urea, creatinine and alkaline ions in clinical samples

Creatinine deiminase has been used in a study to assess the application of a creatinine-sensitive biosensor for hemodialysis control. Creatinine deiminase has also been used in a study to investigate the bioelectronic tongue for the simultaneous determination of urea, creatinine and alkaline ions in clinical samples.

Biochem/physiol Actions

Creatinine deiminase catalyzes the hydrolysis of creatinine to methylhydantoine and ammonia.
