Up-regulated expression of the cbb (sub)I and cbb (sub)II operons during photoheterotrophic growth of ribulose 1,5-bisphosphate carboxylase-oxygenase deletion mutant of Rhodobacter sphaeroides

Research has been conducted on Rhodobacter sphaeroides ribulose 1,5-bisphosphate carboxylase-oxygenase deletion strain. The increase of the gene transcription of Calvin-Benson-Bassham cycle has indicated the existence of a potential physiological effector enhancing the ability of the positive transcription activator to mediate Calvin-Benson-Bassham pathway intermediate.
