Membrane associated poly (A)-containing ribonucleoproteins in Artemia Salina gastrula embryos

Polypeptide chain initiation in eukaryotes: initiation factor MP in Artemia salina embryos.

The activity of IF-MP, a polypeptide chain initiation factor that forms a ternary complex with eukaryotic initiator Met-tRNA and GTP and promotes binding of the initiator to 40S ribosomes, is very low in undeveloped Artemia salina embryos but increases over 20-fold following resumption of development upon hydration of the cysts. The factor is present in both the ribosomal salt wash and high-sp...

A gynandromorph of the brine shrimp, Artemia salina.

S EXUAL mosaics have been reported in three genera of Crustacea. A bilateral mosaic of Carcinus was found to have a testis on one side and a mixed gonad on the other (VEILLET 1945). Gynandromorphs with a testis and ovary have been reported in Homarus (see review by CHACE and MOORE 1959) and in the cladoceran, Simocephalus (BANTA, WOOD, BROWN and INGLE 1939). No intersex or mosaic of Artemia has...

On the metabolism of carotenoids in the crustacean Artemia salina.

Die Zusammensetzung und der Stoffwechsel der Carotinoide in adulten Exemplaren von Artemia salina wurden untersucht. Unabhängig von der Fütterung mit carotinoidfreier Hefe, mit an Oxicarotinoiden reicher Nahrung oder mit Oxocarotinoid-haltigen Algen lassen sich als Hauptpigmente Canthaxanthin (4.4'-Dioxo-/?-carotin) und Echinenon (4-Oxo-/?-carotin) nachweisen. Daneben wur­ den in einer Artemia-...

The Survival of Artemia Salina (l.) in Various Media

A Single-stranded Nucleic Acid-binding Protein from Artemia salina

A protein that binds tightly to single-stranded but not to double-strained nucleic acids has been purified to homogeneity from a high salt wash of ribosomes from cryptobiotic Artemia salina gastrulae. The protein, designated HD40 to indicate a helix-destabilizing protein with a molecular weight of 40,000, is present in the high-salt ribosomal wash at a level of about 2 molecules per 80 S riboso...
