Abstract
The source of nitrogen in the phenazine, iodinin 5, and in 2-aminophenoxazinone 7 in Brevi bacterium iodinum cultures is shown to be primarily from the amide nitrogen of glutamine in experiments with (S)-[CO15NH2]glutamine, [15N]ammonium sulphate, and (S)-[15N]glutamic acid. The biosynthesis of 5 and 7 is closely related; biosynthesis o f 7 like that o f 5 diverts from the shikimic acid pathway at a stage prior to anthranilic acid 8.
