애플리케이션
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.
생화학적/생리학적 작용
Creatinine deiminase catalyzes the hydrolysis of creatinine to methylhydantoine and ammonia.[1]

A precise and sensitive working microflow titration procedure was developed to determine creatinine and ammonia in urine samples. This procedure is based on enzymatic conversion of creatinine, gas diffusional membrane separation of the released ammonia into an acid acceptor stream

Creatinine iminohydrolase (EC 3.5.4.21) quantitatively releases ammonia from flucytosine (5FC) as well as from creatinine. Using 39 sera from eight patients receiving the combination of amphotericin B with 5FC, we demonstrated that this rapid enzymatic reaction provides a valid measure

A flow-injection analysis biosensor system was developed for the amperometric assay of creatinine based on coupled reactions of three immobilized enzymes, using an oxygen electrode as the detection device. The ammonia produced by creatinine deiminase-catalyzed hydrolysis of creatinine was further

In this study, the oxazine 170 perchlorate (O17)-ethylcellulose (EC) membrane was successfully exploited for the fabrication of creatine- and creatinine-sensing membranes. The sensing membrane exhibited a double layer of O17-EC membrane and a layer of enzyme(s) entrapped in the EC
