Application
Creatinine Deiminase microbial has been used:
- to immobilize aminosilylated glass beads based biosensor for ammonia/ammonium and creatinine detection in urine[1]
- in creating creatinine-sensing membrane for biophysical studies[2]
- to investigate the bioelectronic tongue for the simultaneous determination of urea, creatinine and alkaline ions in clinical samples[3]
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.[1]
Physical form
Lyophilized powder containing mannitol as stabilizer
Other Notes
One unit will hydrolyze 1.0 μmole of creatinine to N-methylhydantoin and NH3 per min at pH 7.5 at 37 °C in a coupled system with L-glutamic dehydrogenase.
