| 5'-nucleotidase | <enzyme> A glycoprotein enzyme present in various organs and in many cells. The enzyme catalyses the hydrolysis of a 5'-ribonucleotide to a ribonucleoside and orthophosphate in the presence of water. It is cation-dependent and exists in a membrane-bound and soluble form. Chemical name: 5'-Ribonucleotide phosphohydrolase Registry number: EC 3.1.3.5 (12 Dec 1998) |
| 5-nucleotidase | <biochemistry, enzyme> 5-nucleotidase is a liver enzyme that can be measured in the bloodstream. It can be a specific indicator for liver disease when it is elevated. The normal value is 0 to 1.6 U/L (units per litre). 5-nucleotidase can be elevated in cholestasis, hepatic ischaemia, liver necrosis, liver tumour, hepatitis and the use of hepatotoxic drugs. The assay is performed on a venipuncture specimen. Acronym: 5-NT (19 Jan 1998) |
