UREA AMIDOLYASE - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | urease is a common enzyme in human and animal gastrointestinal and urinary tract bacterial infections, it is not only one of the pathogenic factors of some pathogenic bacteria in human and animals, but also one of the necessary enzymes for the transformation of some nitrogen source putrefaction. It was the first time that a crystal was obtained and a metalloenzyme containing Ni ion was found. Urease is also a non-beneficial component present in soybeans. Urease is a nickel-containing oligase. With absolute specificity, specifically catalyzed by urea water to explain the release of ammonia and carbon dioxide. |
| major properties | an enzyme that is non-covalently linked by two or more identical or non-identical subunits, the vast majority of oligomers contain an even number of subunits, but individual oligomers contain an odd number of subunits, such as luciferase, purine nucleoside phosphorylase contains three subunits, subunits are bound by secondary bonds, easy to separate. |
| source distribution | is widely distributed in the seeds of plants, but rich in soybean and concanavalin. It is also found in the blood and urine of animals. Some microorganisms can also secrete urease. |
| Use | is mainly used for the determination of urea in urine and blood of bai, is a kind of nickel oligodu polymerase. A nickel-containing enzyme, dao, that catalyzes the hydrolysis of urea to produce zhi into carbonic acid and two molecules of ammonia and releases ammonia and carbon dioxide. urease can prevent hepatic coma, urease microcapsules and ion exchange resin microcapsules adsorbent composition of artificial kidney. Used to reduce non-protein nitrogen in blood. used in biochemical studies, clinically used as a diagnostic enzyme for the determination of urea in blood and urine. used to decompose residual urea in wine and inhibit the formation of ethyl carbamate. urea in blood and urine was measured for analysis. Medicine, immunotherapy of hepatic coma, preparation of new artificial kidney, urine microsensor. |
| toxicity | GRAS(FDA § 184.1924,2000). |
| Use limit | is not limited (GMP is limited, FDA § 184.1924.2000). |
| production method | GR for Lactobacillus fermentum, a non-pathogenic, non-toxigenic bacterium. Various culture materials of AS were isolated after pure culture. The product was obtained from soybean powder by acetone extraction, filtration, centrifugation and recrystallization. |
