5′-nucleotidase of chicken liver

Biochimica et Biophysica Acta (BBA) - Enzymology, 1967
1. 1.|5′-Nucleotidase (5′-ribonucleotide phosphophydrolase, EC 3.1.3.5) was partially purified from chicken liver. This is the first time it has been possible to obtain 5′-nucleotidase from the hepatic tissue of uricotelic animals and it was found to be kinetically distinct from 5′-nucleotidases obtained from other sources. 2.

Erythrocyte Pyrimidine 5′‐Nucleotidase

British Journal of Haematology, 1980
Summary In this study 31 family members of a patient with erythrocyte pyrimidine 5′‐nucleotidase deficiency were studied. The activity of this enzyme in their erythrocytes is compared with levels in normal subjects and the problems surrounding heterozygote detection are discussed.

Rat liver 5?-nucleotidase

The Histochemical Journal, 1969
Under assay conditions such that there is minimal interference by lysosomal acid phosphatase, the dephosphorylation of nucleoside-5′-monophosphates (AMP or UMP) by rat-liver homogenates at alkaline pH values is attributable to a Mg2+-dependent enzyme (5′-nucleotidase, EC 3.1.3.5).

5-Nucleotidase activity in lymphocytes

The Histochemical Journal, 1981
Some characteristics of lymphocyte 5'-nucleotidase are reviewed. The optimal conditions for the cytochemical localization of 5'-nucleotidase (AMPase) in the mouse lymphocyte have been established. Quantitative monitoring of the effects of fixation and the components of the cytochemical medium showed that cytochemistry can be performed under conditions ...

Micrococcus radiodurans 5′-nucleotidase

Biochimica et Biophysica Acta (BBA) - Enzymology, 1973
Abstract A 5′-nucleotidase (5′-ribonucleotide phosphohydrolase, EC 3.1.3.5) isolated from Micrococcus radiodurans appears to have properties more closely resembling some of the corresponding vertebrate enzymes than the reported bacterial enzymes. The M. radiodurans enzyme is a strict nucleoside 5′-phosphomonoesterase with a pH optimum between 8 and 9.

5′-Nucleotidase and phosphatases in human brain

Clinica Chimica Acta, 1964
Abstract The activities of five enzymes catalysing release of phosphate have been determined in homogenates from different regions of human brain and cord; all enzymes showed activities within a small range of absolute values. The enzymes showed similar activities in autopsy and biopsy material.

5′-Nucleotidase Activities in Human Fetus

Neonatology, 1985
Specific 5′-nucleotidase (5′-N) activity in 17 human fetuses was systemically studied in order to get basic values of the enzyme activity. A wide spectrum of 5′-N activity among the organs was revealed. Very strong activity was found in placenta (42.62 ± 19.24 nmol adenosine/mg protein/min), skeletal muscle (31.80 ± 11.10) and skin (27.31 ± 13.00 ...

Ecto-Enzyme of Granulocytes: 5′-Nucleotidase

Science, 1974
The 5′-nucleotidase of guinea pig polymorphonuclear leukocytes is localized exclusively on the plasma membrane of intact cells. The active site of this enzyme faces the external medium, not the cytoplasm.

A radioassay for pyrimidine-5′-nucleotidase activity

Clinica Chimica Acta, 1978
A simple method for the determination of pyrimidine-5'-nucleotidase activity in red cells is described. The radioactive uridine released after incubation with [5-3H]] uridine 5-monophosphate (UMP) is separated on DEAE-cellulose paper and counted. This method does not require preliminary dialysis of the hemolysate and is 50-fold more sensitive than that
