Figure 5From: Comparative genomic analysis of carbon and nitrogen assimilation mechanisms in three indigenous bioleaching bacteria: predictions and validationsSchematic diagram of the A. thiooxidans DSM17318 genomic region containing putative nitrate assimilation genes. The following genes are indicated: ntrA encodes the periplasmic component of the nitrate transport system; narK encodes a nitrate/nitrite transporter; nirB encodes a nitrite reductase, which is interrupted by the transposase tnpA; nirD encodes the nitrite reductase small subunit; narB encodes a nitrate reductase; cysG encodes an uroporphyrin-III C-methyltransferase; and nasT encodes a nitrate assimilation system regulator.Back to article page
