Aerobic and anaerobic regulation in Rhodobacter sphaeroides 2.4.1: the role of the fnrL gene.

Journal of bacteriology - 1 Nov 1995

Zeilstra-Ryalls J H, Kaplan S

Abstract excerpt

In Rhodobacter sphaeroides 2.4.1, the cellular requirements for 5-aminolevulinic acid (ALA) are in part regulated by the level of ALA synthase activity, which is encoded by the hemA and hemT genes. Under standard growth conditions, only the hemA gene is transcribed, and the level of ALA synthase activity varies in response to oxygen tension. The presence of an FNR consensus sequence upstream of hemA suggested...
