Assimilation of nitrate and nitrite in response to nitrogen stress. Metabolic module u1 representing nitrate/nitrite assimilation consisting of 8 reactions and 2 metabolites with a score of 13.9 and a q-value of <0.004. Squares represent enzymatic reactions and circles represent metabolites. No definitive claims can be made about fluxes, so arrows are only indicative and taken from the identity or context of the relevant reaction.
