| anemonefish symbiosis: vulnerability and resistance of fish to the toxin of the sea anemone. | protein toxins (20 kd molecular mass) causing lysis of human erythrocytes were isolated from sea anemones (heteractis magnifica, madang, papua new guinea, and entacmaea quadricolor, red sea), which host anemonefish (amphiprion sp.). these toxins are also ichthyotoxic. freshwater and marine fish exposed to toxin concentrations of 0.5 micrograms/ml water were killed within 2 hr and exhibited extensive pathological alterations of the gill filaments. amphiprion species, e.g. clarkii and percula, whi ... | 1994 | 7801342 |
| amino acid sequence studies on cytolytic toxins from sea anemone heteractis magnifica, entacmaea quadricolor and stichodactyla mertensii (anthozoa). | the complete amino acid sequence of a cytolytic toxin, hmt, isolated from sea anemone heteractis magnifica was determined. it is composed of 177 amino acid residues and lacks half-cystines. partial n-terminal sequences of three other cytolysins from entacmaea quadricolor (ent) and stichodactyla mertensii (smt-1 and smt-2) were also determined. comparing these sequences with those of other sea anemone cytolysins, a high degree of homology was observed. | 2000 | 10665806 |
