Purification and properties of GTP:GTP guanylyltransferase from encysted embryos of the brine shrimp Artemia.
GTP:GTP guanylyltransferase has been purified from the yolk platelets of Artemia cysts. The 480-kDa enzyme catalyzes the reversible reaction 2GTP<==>Gp4G + PPi and contains immunologically related polypeptides of 142, 88, and 45 kDa and a distinct 80-kDa component. The 88 and 45 kDa species can be covalently labeled with [alpha-32P]GTP. Even in crude extracts, the enzyme appears to be partially...
متن کاملNucleotide metabolism during brine shrimp embryogenesis.
Changes in the amounts of acid-soluble nucleotides during embryonic development of the encysted egg of the brine shrimp, Artemia salina, have been determined. Significant quantities of diguanosine tetraphosphate, the most abundant compound in the nucleotide pool, are apparently not utilized until hatching, at which time the amount falls precipitously. Diguanosine triphosphate, a homologue of th...
متن کاملToxicity Effect of Silver Nanoparticles in Brine Shrimp Artemia
The present study revealed the toxic effect of silver nanoparticles (AgNPs) in Artemia nauplii and evaluated the mortality rate, hatching percentage, and genotoxic effect in Artemia nauplii/cysts. The AgNPs were commercially purchased and characterized using field emission scanning electron microscope with energy dispersive X-ray spectroscopy. Nanoparticles were spherical in nature and with siz...
متن کاملMolecular phylogenetics and asexuality in the brine shrimp Artemia.
Explaining cases of long-term persistence of parthenogenesis has proven an arduous task for evolutionary biologists. Interpreting sexual-asexual interactions though has recently advanced owing to methodological design, increased taxon sampling and choice of model organisms. We inferred the phylogeny of Artemia, a halophilic branchiopod genus of sexual and parthenogenetic forms with cosmopolitan...
متن کاملEvaluation of Brine Shrimp Lethality of Cinnamomum Species
Cinnamomum species have long been used as spices. The preliminary bioactive constituent’s identification and brine shrimp lethality activities of ethanolic extracts of seven Cinnamomum species viz., C. travancoricum, C. walaiwarense, C. wightii, C. verum, C. sulphuratum, C. riparium, and C. perrottetii were evaluated in this study. The results of cytotoxic activity of the bark extracts of seven...
