Freshwater sponges in Estonia: genetic and morphological identification
TLDR
The DNA analysis showed the presence of three spongillid species in Estonia: Ephydatia fluviatilis, EphYDatia muelleri, and Spongilla lacustris.
The (2'-5')oligoadenylate synthetase is present in the lowest multicellular organisms, the marine sponges. Demonstration of the existence and identification of its reaction products.
TLDR
It is concluded, that the (2'-5')An system has evolved from receptors and enzymes involved in cell adhesion and/or growth control in the marine sponge Geodia cydonium.
ATP N-glycosidase - a novel ATP-converting activity from a marine sponge Axinella polypoides.
TLDR
The biochemical properties of ATP N-glycosidase show similarities with previously described adenine-specific nucleosidases; however, the pattern of its biochemical characteristics does not match with that of any of those enzymes.
Induction of (2'-5')oligoadenylate synthetase in the marine sponges Suberites domuncula and Geodia cydonium by the bacterial endotoxin lipopolysaccharide.
TLDR
It is postulated that in sponges the (2-5)A synthetase is involved in antimicrobial defense of the animals.
Identification of the reaction products of (2'-5')oligoadenylate synthetase in the marine sponge.
TLDR
It is proposed that the (2'-5')A system is involved in a cytokine-mediated pathway and/or in a protection system against viruses, present in the marine environment.
