A new technique for visualizing the dynamics of nitrate (NO3-) and nitrite (NO2-), both markers of nitric oxide in a cell, has been created by researchers. Nitric oxide is a critical second messenger ...
The nitrate/nitrite porter (NNP) family of membrane proteins evolved to efficiently translocate the ionic molecules NO 3 − and NO 2 − across the membrane 4,5. Two nitrate/nitrite transport proteins ...
