Abstract excerpt

The hemA gene codes for one of two synthases in Rhodobacter sphaeroides 2.4.1 which catalyze the formation of 5-aminolevulinic acid. We have examined the role of PrrA, a DNA binding protein that is associated with the metabolic switch between aerobic growth and anoxygenic photosynthetic growth, in hemA expression and found that hemA transcription is directly activated by PrrA. Using electrophoretic mobility shift...
