摘要：

The genome of Alcaligenes eutrophus H16 contains two functional, highly homologous clusters of genes (cfx genes) for at least six Calvin cycle enzymes, with one cluster located on the chromosome and the other on megaplasmid pHG1. The genes within each cluster presumably belong to a single large operon of about 11 kilobase pairs (kb) in size. Both operons form a cfx regulon that is controlled by the chromosomally encoded regulatory gene cfxR. The product of cfxR seems to be a transcriptional activator. Occurrence of isoenzymes within the central carbon metabolism of the organism is a consequence of this unusual genetic setup.
