Adenosine- and uridine-cytidine kinases, purine-nucleoside phosphorylase, hypoxanthine-guanine phosphoribosyl transferase, and several related enzymes, are components of the salvage pathways which reduce the loss of intracellular purine and pyrimidin

1. 1. Purine nucleoside phosphorylase (purine nucleoside: orthophosphate ribosyl transferase, EC 2.4.2.1) was purified to electrophoretic homogeneity from the liver of Camelus dromedarius . 2. 2. The enzyme appears to be a dimer with a 44,000 subunit
Among a series of purine nucleosides, inosine was found to be phosphorylated at the highest rate by crude extracts of the cyanobacterium Spirulina platensis . The inosine phosphorylating activity could be separated from hypoxanthine-guanine phosphori

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 transfe

A cytosolic 5'-nucleotidase, acting preferentially on IMP and GMP, has been isolated from human colon carcinoma extracts. This enzyme activity catalyzes also the transfer of the phosphate group of 5'-nucleoside monophosphates (mainly, 5'-IMP, 5'-GMP,

The transmural distribution of the adenosine-generating enzyme 5'-nucleotidase (5'N) and of the adenosine-degrading enzymes adenosine deaminase (ADA), AMP deaminase (AMP-D) and adenosine kinase (Ado-K) were determined across the walls of left and rig

Adenosine has been measured at the nanomolar level by an enzymatic radioactive assay. The nucleoside is converted into [U-14C]ribose-labeled inosine via the following reactions: adenosine + H2O----adenine + ribose (adenosine nucleosidase); adenine +
