  3. 2. Amine oxidases in dental pulp : a study with special regard to a semicarbazide-sensitive amine oxidase with catalytic potency towards serotonin

    Sammanfattning : The amine oxidizing capacity of piglet dental pulp tissue has been investigated. At least six separate enzyme activities could be distinguished:- a soluble semicarbazide-sensitive (SSAO) activity towards benzylamine, most likely to be derived from the content of blood plasma within the pulp tissue;- a soluble pulp tissue SSAO activity with most properties in common with the plasma enzyme, however with great efficiency not only regarding benzylamine but also tryptamine;- a tissue bound SSAO activity with activity towards benzylamine, tryptamine, tyramine and ß-phenylethylamine;- a tissue bound semicarbazide-sensitive activity towards serotonin (SSA0-5HT) (a combination of properties never reported before);- a mitochondrially bound and clorgyline-sensitive monoamine oxidase-A (MAO-A) activity with activity towards serotonin;- a mitochondrially bound and deprenyl-sensitive MAO-B activity with activity towards e.
