Rhodobacter sphaeroides was found to contain two clusters of chromosomally encoded CO2 fixation structural genes. Recent studies indicate that genes within each cluster are cotranscribed, suggesting that there is a single long transcript for each cluster. All of the genes have been sequenced, homologies noted, specific mutations obtained, and interesting upstream regulatory sequences found. Site-directed mutagenesis studies of the Anacystis rbcS has begun to provide information relative to RubisCO structure and function. In addition, RubisCO-negative strains of photosynthetic bacteria have been constructed to screen for altered RubisCO sequences.
