Cracks in the beta -can: Fluorescent proteins from Anemonia sulcata (Anthozoa, Actinaria)

The Stimulus to Feeding in Anemonia Sulcata

First evidence of antimicrobial activity of neurotoxin 2 from Anemonia sulcata (Cnidaria)

We investigated the antibacterial activity of Anemonia sulcata (Cnidaria, Anthozoa) tentacle and body acidic extracts. Biochemical purification consisted of first step on solid phase Sep-Pak C8 column followed by several HPLC runs on C18 column using different conditions. Anti-Micrococcus lysodeikticus activity has been detected in 40 % acetonitrile fractions. The resulting purified molecule fr...

In Vitro Anti-Inflammatory and Cytotoxic Effects of Aqueous Extracts from the Edible Sea Anemones Anemonia sulcata and Actinia equina

Marine invertebrates have been attracting the attention of researchers for their application in nutrition, agriculture, and the pharmaceutical industry, among others. Concerning sea anemones (Cnidaria), little is known regarding their metabolic profiles and potential value as a source of pharmacologically-active agents. In this work, the chemical profiles of two species of sea anemones Actinia ...

Alternative cyclization in GFP-like proteins family. The formation and structure of the chromophore of a purple chromoprotein from Anemonia sulcata.

Anemonia sulcata purple protein (asFP595) belongs to a family of green fluorescent protein (GFP)-like proteins from the Anthozoa species. Similar to GFP, asFP595 apparently forms its chromophore by modifying amino acids within its polypeptide chain. Until now, the GFP-like proteins from Anthozoa were thought to contain chromophores with the same imidazolidinone core as GFP. Mass spectral analys...

1H-n.m.r. study of the solution properties and secondary structure of neurotoxin III from the sea anemone Anemonia sulcata.

The solution properties, secondary structure and global fold of the 27-residue polypeptide neurotoxin III (ATX III), from the sea anemone Anemonia sulcata, have been investigated using high-resolution 1H-n.m.r. spectroscopy. Studies of the concentration dependence of the n.m.r. spectrum indicate that the molecule self-associates in the millimolar concentration range useable for n.m.r. analysis,...
