Evidence of dopa in the nerves of sea anemones

, : Evidence of dopa in the nerves of sea anemones. Journal of Neural Transmission 57(1-2): 75-84

Using high pressure liquid chromatography, an analysis of the presence of catechol-derivatrives in the sea anemones Metridium senile and Tealia felina, established the presence of dopa, 5-OH-dopa and 5-S-cysteinyldopa. 2-S-cysteinyldopa and 2,5-diSS-cysteinyldopa occurred in Metridium. Two unknown substances were found in the tentacles of Metridium and in the tentacles of some specimens of Tealia. Neither catecholamines nor serotonin could be traced in detectable amounts. No dopa-decarboxylase could be demonstrated by the assay performed in this investigation. 6-OH-dopa, 6-OH-dopamine and reserpine had no effect on the formaldehyde-induced fluorescence of the subepithelial tentacular nerve net of Tealia. Thus, the tentacular nerve net of sea anemones contains dopa, but neither catecholamines nor serotonin. The localization of the other compounds is not yet established.
