Cloned(Commentary)

Cloned (Comment)	Organism
expressed in cells the nrtABCD deletion mutant NA3 of Synechococcus elongatus which restores the ability of the cell to grow on nitrate as sole nitrogen source	Nostoc punctiforme

Inhibitors

Inhibitors	Comment	Organism	Structure
additional information	nitrate uptake is inhibited by addition of ammonium ions to the medium, while uptake of nitrite is not, results indicate that the transporter is not directly inhibited by ammonium ions	Nostoc punctiforme
