entitled “Functional Characterization of the FNT Family Nitrite Transporter of Marine Picocyanobacteria” is a very interesting piece of work since it shows the functional characterization as nitrite transporter of several nitM proteins from different picocyanobacteria, showing also fruitful comparisons of their sequences that lead to characterize the c-terminal region of a-cyanobacterial NitM proteins as an inhibitory domain of nitrite transport.
