Some properties of monoamine oxidase in carp heart.
Studies using clorgyline, deprenyl and semicarbazide as inhibitors showed that carp heart homogenate contained a new type of monoamine oxidase (MAO) and a clorgyline- and deprenyl-resistant amine oxidase (CRAO). The deamination of monoamines by carp heart MAO proceeded in two steps by a double-displacement (ping-pong) mechanism. The Km values of the MAO for oxygen (K0 values) with tyramine, 5-hydroxytryptamine (5-HT) and beta-phenylethylamine (PEA) as substrates were identical (59 microM).
