摘要：

Disruption of the gene nrtD, encoding a component of the nitrate transport system of Synechococcus sp. PCC 7942, not only impaired nitrate transport but also abolished active nitrite transport. Passive entrance into the cell of nitrous acid was unaffected in the nrtD mutants. These results show that the nrtD gene is involved in the active transport of nitrite. Nitrate and active nitrite transport in Synechococcus are thus mediated by a common permease.
