Human Endogenous Metabolite

In Vitro NSC 16590 (α-Aminoisobutyric acid , AIB) inhibits the production of endogenous ethylene in the cotyledonary segments of cocklebur (Xanthium pennsylvanicum Wallr.) seeds most strongly. NSC 16590 at 4 mM inhibits the formation of ethylene by about 50%, although the O2 uptake of the segments is not affected even at 20 mM. NSC 16590 also inhibits ethylene formation in the stem segments of etiolated pea (Pisum satiuum L. cv. Alaska) seedlings. Kinetic analysis with cell free extracts from etiolated pea shoots reveals that NSC 16590 competitively inhibits the conversion of ACC into ethylene[1].
