Metabolism of phenylethylamine in rat isolated perfused lung: evidence for monoamine oxidase 'type B' in lung.
Phenylethylamine is inactivated in a single passage through rat lung tissue by a process of uptake and deamination by a monoamine oxidase 'type B'. This enzyme is particularly susceptible to inhibition by deprenil and less sensitive to clorgyline. The monoamine oxidase of the lung, like that of other rat tissues, can be differentiated into 'type A' and 'type B' which appear to operate independently in the organized tissue.
