Abstract
Abstract Polyphysa peniculus growing in artificial seawater methylates arsenate to produce a dimethylarsenic derivative, probably dimethylarsinate. When L-methionine-methyl-d 3 is added to the culture the CD 3 label is incorporated intact in the dimethylarsenic compound to a considerable extent, indicating that S-adenosylmethionine, or some related sulphonium compound, is involved in the biological methylation. Conclusive evidence of the CD 3 incorporation was provided by using a specially developed hydride generation-gas chromatography-mass spectrometry methodology.
