Alpha-alpha'-dipyridyl or ortho-phenanthroline stimulation of the soluble reduced nicotinamide adenine dinucleotide oxidase from Bacillus subtilis spores and dipicolinic acid inhibition of the stimulated enzymes

K Tochikubo. J Bacteriol. 1974 Mar.

Abstract

Soluble reduced nicotinamide adenine dinucleotide oxidase activity in extracts of Bacillus subtilis spores was stimulated by the addition of not only flavine mononucleotide (FMN) or flavine adenine dinucleotide (FAD) but also alpha-alpha'-dipyridyl or o-phenanthroline. These chelating agents showed stronger effect on the enzyme from spores than on that from vegetative cells. Activity stimulated by alpha-alpha'-dipyridyl or o-phenanthroline was inhibited by atabrine or dipicolinic acid, whereas FMN or FAD stimulation was inhibited only by atabrine.
