Alginate Biosynthesis in Azotobacter vinelandii: Overview of Molecular Mechanisms in Connection with the Oxygen Availability

Figure 5

Regulation of alginate biosynthetic genes in A. vinelandii (modified according to reference [40]). Promoters are indicated as banners; mRNAs are indicated as dotted boxes; solid lines indicate the reported mechanism of regulation, and dashed lines indicate unknown mechanism of gene regulation; arrows indicate positive regulation and T-shaped bars indicate negative regulation. OM: outer membrane; PG: peptidoglycan; IM: inner membrane. See text for a more detailed description.
