Exploration of Nitrate Reductase Metabolic Pathway in Corynebacterium pseudotuberculosis

Figure 2

Nitrate locus from C. pseudotuberculosis biovar Equi. (a) This locus contains the following: genes encoding the nitrate reductase narK, narG, narH, narJ, and narI, and the genes encoding the molybdopterins moeB, moaE, molB, molA, moeY, moaC, moeA, and moaA. Insertion between ansA and rpsH: genes encoding the nitrate reductase are lacking in nitrate-negative C. pseudotuberculosis biovar Ovis strains. Arrows represent open reading frames and their orientations. (b) Bacterial nitrate respiration. The NarG and NarH bind to the membrane via the interaction between a hydrophobic patch of NarH and NarI which is buried within the membrane. The NarJis a chaperone that is involved in folding, maturation, and molybdenum cofactor insertion of nitrate reductase.
