Abstract Some kinetics of the oxygen requirement of amine oxidases
have been investigated using bovine plasma monoamine oxidase (PAO)
and pea seedling diamine oxidase (DAO). A system is described for
studying enzyme reactions under controlled oxygen tension and in an
O₂-free N₂ atmosphere.
O₂ Km values were determined at two different levels of amine
concentration for both PAO and DAO. The apparent O₂ Km values
were found to vary with amine concentration and were in the order
of 10⁻⁴ to 10⁻⁶ M depending on the enzyme and amine present in the
reaction mixture.
Ratios of moles of aldehyde product formed per mole of enzyme
were determined under anaerobic conditions for PAO and DAO. The
molar ratios were found to be approximately one mole of aldehyde
per mole of enzyme in an O₂-free atmosphere for both enzymes.
This suggests that the enzymes may produce a mole equivalent of
aldehyde in the absence of oxygen.
