[On the protein composition of ribonucleoprotein particles before and after fertilization fo sea urchin eggs (Echinus esculentus)].
Experiments indicate that eggs and embryos of the North Sea sea urchin Echinus esculentus are excellent material to investigate the regulation of protein synthesis before and after fertilization. The dormant egg contains several proteins which are absent from embryos. Such additional proteins have been detected on the small ribosomal subunits, in the salt wash of whole ribosomes, and associated...
متن کاملThe Physiology of Echinus Esculentus Spermatozoa
INTRODUCTION Ripe sea-urchin spermatozoa are motionless in undiluted semen and intensely active when shed or artificially diluted. This activity is of short duration, presumably because the amount of energy-producing material within the spermatozoon is small, and because in pure sea water all of the endogenous substrate may not be available for combustion (Gray, 1928a, b, 1931). If semen is dil...

متن کاملBacterial Clearance in the Sea Urchin , Strongylocentrotus
approved: Redacted for Privacy __ Dr. Christopher J. Bayne Characteristics of bacterial clearance were investigated in the purple sea urchin, Strongylocentrotus purpuratus (Echinodermata: Echinoidea). Primary clearance kinetics were determined for three bacteria, a marine Gram negative motile rod, a marine Gram positive nonmotile rod, and a fresh water fish pathogen, Aeromonas salmonicida. Vari...
متن کاملNovel Antimicrobial Peptides EeCentrocins 1, 2 and EeStrongylocin 2 from the Edible Sea Urchin Echinus esculentus Have 6-Br-Trp Post-Translational Modifications
The global problem of microbial resistance to antibiotics has resulted in an urgent need to develop new antimicrobial agents. Natural antimicrobial peptides are considered promising candidates for drug development. Echinoderms, which rely on innate immunity factors in the defence against harmful microorganisms, are sources of novel antimicrobial peptides. This study aimed to isolate and charact...
