Abstract

The topological arrangements of nitrate and nitrite reductases in bacterianecessitate the synthesis of transporter proteins that carry the Nitrogen oxyanions across the cytoplasmic membrane. For assimilation of nitrate landnitrite) there are two types of uptake system known: ABC transporters thatare driven by ATP hydrolysis, and secondary transporters reliant on a proton motive force. Proteins homologous to the latter type of transporter are also involved in nitrate and nitrite transport in dissimilatory processes such as denitrification. These proteins belong to the NarK family, which is a branch of the Major Facilitator Superfamily. The mechanism and substrate specificity of transport via these proteins is unknown, but is discussed inthe light of sequence analysis of members of the NarK family. A hypothesisfor nitrate and nitrite transport is proposed based on the finding that there are two distinct types of NarK.
