Abstract

The photosynthetic diazotrophs, such as Rhodopseudomonas palustris , can utilize light energy to drive the conversion of carbon dioxide (CO 2 ) to a much more powerful greenhouse gas methane (CH 4 ) by Fe-only nitrogenase, which is strictly regulated in response to the ammonium, a substrate of glutamine synthetase for the biosynthesis of glutamine. However, the primary glutamine synthetase for ammonium assimilation and its role in nitrogenase regulation remain unclear in R. palustris .
