Abstract

Regulation of photosynthetic membrane synthesis in Rhodobocter sphoeroides 2.4.1 is dependent on the interactions of numerous regulatory elements, with two of the most important being the cbb3 terminal oxidase and the PrrBAC two-component regulatory system. Here, we reveal that the cbb3 terminal oxidase possesses extensive, additional regulatory activities under anaerobic conditions, and that the PrrBAC system is further involved in the regulation of the expression of more than 20% of the R. sphaeroides genome under anaerobic conditions, extending well beyond functions related to redox gene expression.
