title: [Monoamine oxidase type B and the function of Ca2+, Mg2+-dependent adenosine triphosphatase of preparations of sarcoplasmic reticulum vesicles].
abstract: Oxidative deamination by monoamine oxidases of B type in the preparations of sarcoplasmic reticulum vesicles from rabbit skeletal muscles of beta-phenylethylamine or benzylamine was accompanied by a decrease of both the active transport of Ca2+ into the vesicles and Ca2+, Mg2+-dependent ATP-ase activity. This decrease was prevented by pretreatment of the vesicles with deprenyl, a specific monoamine oxidase type B inhibitor. The aldehydes formed in the course of enzymatic deamination of the substrates of type B, monoamine oxidases, are considered as possible participants in the regulation of Ca2+, Mg2+-dependent ATP-ase activity.
