Abstract
Studies on the nitrite uptake capability of a mutant of Synechococcus sp. s train PCC 7942 lacking the ATP-binding cassette-type nitrate-nitrite-bispec ific transporter revealed the occurrence of a nitrite-specific active trans port system with an apparent K-m (NO2-) of about 20 mu M Similar to the nit rate-nitrite-bispecific transporter, the nitrite-specific transporter was r eversibly inhibited by ammonium in the medium.
