Why myotoxin-containing snake venoms possess powerful nucleotidases? [PDF]

Biochemical and Biophysical Research Communications, 2013
The venom of the snake Bothrops asper causes muscle necrosis, pain and inflammation. This venom contains myotoxins which cause an increase in intracellular Ca(2+) concentration and release of K(+) and ATP from myotubes.

Serum 5′-nucleotidase

Clinical Biochemistry, 1970
Summary 1. Sequential studies of serum 5′-nucleotidase (EC 3.1.3.5) in association with other enzymes in patients with malignant diseases are presented. 2. Evidence is given for the specific significance of the assay of 5′-nucleotidase in serum which is a sensitive monitor for the appearance of metastases in liver. 3.

The Bifunctional Cytosolic 5′-Nucleotidase: Regulation of the Phosphotransferase and Nucleotidase Activities

Archives of Biochemistry and Biophysics, 1994
The cytosolic 5'-nucleotidase specific for IMP, GMP, and their deoxyderivatives has been purified approximately 1000 times from calf thymus. The enzyme, in the presence of a suitable nucleoside, can act as a phosphotransferase, catalyzing the transfer of the phosphate moiety from a nucleoside monophosphate donor to a nucleoside acceptor, thus operating

Postictal serum nucleotidases activities in patients with epilepsy [PDF]

Epilepsy Research, 2009
Adenosine, a potent anticonvulsant, can be produced in the body by the hydrolysis of adenine nucleotides through the action of ecto- or soluble nucleotidases. Changes in nucleotide hydrolysis occur after pentylenetetrazol-induced epileptic events.

The 5′-Nucleotidases and Cyclic Phosphodiesterases (3′-Nucleotidases) of the Enterobacteriaceae

Journal of Bacteriology, 1968
All members of the Enterobacteriaceae possess distinct 5′-nucleotidases and cyclic phosphodiesterases (3′-nucleotidases) that can be differentiated from the acid and alkaline phosphatases and the acid sugar hydrolases. The nucleotidases and cyclic phosphodiesterases of the various Enterobacteriaceae

Diphosphopyridine Nucleotidase and Acute Glomerulonephritis

Archives of Internal Medicine, 1962
The presence of diphosphopyridine nucleotidase (DPNase) in filtrates of cultures of hemolytic streptococci was first described in 1956. 1,2 Among several bacterial species studied, only streptococci of Groups A, C, and G produced this extracellular enzyme.

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.
