Abstract

An extrapineal enzyme that N-acetylates a variety of indole and catechol alkylamines, including the psychoactive drugs mescaline and d-amphetamine, has been partially purified from rat brain. This enzymatic activity has a distinct pH optimum, is linear with incubation time and protein concetration, and is abolished by heating. Purification is approximately ten fold with ammonium sulfate precipitation and column chromatography, yielding a specific activity of 7936 pmoles of product per mg of protein per hour with tryptamine as substrate.
