Diguanosinetetraphosphate guanylohydrolase in Artemia salina

Biochimica et Biophysica Acta (BBA) - Enzymology, 1974
1. The diguanosinetetraphosphate guanylohydrolase (EC 3.6.1.17) of Artemia salina has been found to be located in the cytosol while its substrate, diguanosine tetraphosphate, is in the sediment. 2. Two spectrophotometric methods have been developed to study this enzyme.

GMP reductase in Artemia salina

Biochimica et Biophysica Acta (BBA) - Enzymology, 1974
Abstract 1. 1. A GMP reductase (NADPH:GMP oxidoreductase (deaminating), EC 1.6.6.8) activity has been characterized, and partially purified, in Artemia salina extracts. The enzyme is specific for NADPH, has a k m of 0.01 mM for GMP, is maximally active at a pH value of approx. 8.5, requires thiol groups and is resistant to heating at

The hemoglobins of Artemia salina—III. Characterization

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
1. 1. Three brine shrimp hemoglobins (Hb-1, Hb-2, and Hb-3) have the same sedimentation coefficient (S20,w = 11.3S). The three native molecules have a molecular weight of about 230,000 and are stable at ionic strength 0.04–2.04 and pH 7.5–9.8. 2. 2.

Dinucleosidasetetraphosphatase in rat liver and Artemia salina

Biochimica et Biophysica Acta (BBA) - Enzymology, 1976
A comparative study of an enzymatic activity present in Artemia salina and rat liver which specifically splits dinucleoside tetraphosphates is presented. All the purine and pyrimidine dinucleoside tetraphosphates tested, i.e. diadenosine, diguanosine, dixanthosine and diuridine tetraphosphates, were substrates of both enzymes with similar maximum ...

Physical properties of Artemia salina ribosomes

Biochemistry, 1978
Eukaryotic ribosomes were isolated from the cryptobiotic embryos and from the further-developed free-swimming nauplii of the brine shrimp Artemia salina. Analytical boundary sedimentation and photon correlation spectroscopy yielded, respectively, the standard sedimentation and diffusion coefficients at infinite dilution, s degrees 20,w = 81 +/- 1 S and

Accumulation of cadmium by Artemia salina

Marine Biology, 1979
The relative importance of accumulation of cadmium by Artemia salina (L.) directly from solution and from ingested food has been studied at 3 cadmium concentrations (0.1, 1 and 10 ppm) under controlled experimental conditions. At each cadmium concentration, A.

Functional properties of the hemoglobins of Artemia salina L.

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 1. 1. In hypoxic conditions Artemia salina L. forms 3 hemoglobins, which until now had only been characterized by their electrophoretic mobility. 2. 2. We have analysed the oxygen-binding properties of these 3 hemoglobins. 3. 3.
