ABSTRACT
A further division into "flavin" and "nonflavin" amine oxidases can be made. The former group is mainly, if not exclusively, associated with mitochondria and will not be considered in the present chapter; a review of their properties can be found in Reference 1. The latter group, designated amine:oxygen oxidoreductase (deaminating), EC 1.4.3.6, has been subdivided into mono-and diamine oxidases according to substrate specificity and the action of inhibitor^.^ This subdivision seems outdated to the reviewers who will consider all members of this group together. A general property of the "nonflavin" amine oxidases is that they contain copper as a cofactor and probably this is a better way to classify them. In the present review, the term "amine oxidases" implies copper-containing oxidases.
