Abstract

An enzyme which N-methylates various indole(ethyl)amine substrates was isolated from brain, separated from the pituitary and the pineal glands. It appeared localized in the supernatant and synaptosomal areas after discontinuous sucrose-gradient ultracentrifugation. This is the first demonstration of the enzyme in brain.
