Abstract

Abstract Some structural and biochemical characteristics of polyamine oxidase (PAO) purified from maize shoots have been examined. The enzyme has only alanine as N- terminal amino acid and its N-terminal sequence shows a significant degree of homology with tryptophan 2-monooxygenase from Pseudomonas syringae pv. savastanoi. The pH optimum for the stability of the native enzyme is 5, similar to that of the barley leaf enzyme. ...
